Summary: Need to reset it from time to time.
Review: I was thrilled when I just got the iPAQ4155. It is so stylish and powerful. Things changed suddenly after just two days, the iPAQ "died" for no reason. No matter which button I pused, it did not come up. First I thought it was because the battery ran out (butit shouldn't for I checked there was still 40% of battery when I turned it off one hour ago.), then I plugged in the DC power supply and still the same thing. I was so frustrated and worried about the painful things of sending it back for repair. I even regretted that I shouldn't have bought it online (from Amazon) otherwise I could just dropped in a store to return it. After all these frustration, I sought the last resort before packing it: hard reset and it worked! As expected, all my installed applications and files were gone!!!The same thing has happened a couple of times in the last two days. Now I learned that I don't need to hard reset it, a soft reset will do! But it's still extremely disturbing and I don't know whether eventually even the reset button won't work ... Anyone else has the same experience? And any hint about why? I treated the little gadget very nicely -- carrying it in a leather belt case!

Summary: Great functionality. Poor reliability
Review: This product is really full of features, but the screen cracked twice by itself in one month.

Summary: Awesome!
Review: Everything I expected AND MORE in this little pocket pc. All the functionalities you need in your everyday life as well as everything you could possibly wish for in a portable device: WiFi, Bluetooth, IR, etc. I couldn't be more pleased about this device! Highly recommended for all users!!!

Summary: All-in-all a great product (especially for only $450)
Review: I have very few complaints with my iPAQ. I've had it for about a month now, and using it in conjunction w/ my Bluetooth enabled Sony Ericsson T610 has been pretty sweet. Like others have said, the battery life is nothing great. A little more memory would be nice as well. But the battery life and memory isn't sub-par; it's current with the market right now. Another thing is the FileStore. Prior to this, I had the 1945, which has the same dimensions (.01cm smaller?) and similar feature set (minus Wi-Fi). The FileStore (an area of memory that isn't erased when if you must hard reset) is only 3mb on the 4155, compared to 13mb on my 1945. I love the fact that it fits in my scrub pocket, and obviously the wi-fi is great. I have gone into Starbucks and connected so effortlessly that my email was synced before I placed my order. If you get this (which if you want to have the ability to use WiFi, Bluetooth all in a PPC you should get this one) I would suggest getting one or two SD cards. I currently have a 256mb card, and sometimes it even feels too small. One last thing: missing the CF card slot doesn't seem that important when you have the SDIO ability. I'm hoping to see more peripherals built using this standard in the next year.

Summary: Great Device but poor IRD
Review: I have the h4155. It is my first handheld device. I ABSOLUTELY love it! I have wifi in my home and it connects to it without a hitch. I also have a Pharos BT GPS device that works great with it. It uses com 6 though, despite everyone saying its supposed to use com 8. The IRD is a problem on this ipaq becuase its on the bottom of it! You have to turn it upside down to use the IR. I downloaded TV Remote controller from pdawin, which works fine, but I have to turn the h4155 upside down to use it, and it only sends a signal up to 5 feet and has to be in line of sight. I love everything else about it. The colors are good, and I have not noticed a yellow tint that others speak of. The sound quality is pretty good also.

Summary: Finally what I've wanted from a PDA
Review: The new iPAQ 4155 is what I've been looking for. I've hopped around from Palm OS to Pocket PC, prefering the Pocket PC desktop integration and OS but finding that most of the high-powered ones were just way to big to carry around. The 4155 is TINY - smaller than my Clie I replaced and light! Easy to carry around, I don't even notice it in my pocket. The screen is bright and crisp. The 400mhz Intel processor is plenty for my needs. I've played games on it, emulated an old Atari, handled all my work, and linked it to databases with no problem. The integrated wireless was the selling point for me. I'm a wireless engineer, so it helps to be able to carry around such a small device with built-in 802.11b. My only complaint is that it does not allow you to manually set the SSID information if it automatically detects wireless network SSIDs, but that probably won't be a big problem for most users. Again, this is the PERFECT handheld. I've finally found a handheld I absolutely love - and I've been looking since the original Palm Pilot.

Summary: Tiny, Stable, and Fast
Review: I've had several PPC's, and this one is by far the best. The OS is stable compared to prior versions, the processor handles media clips with ease, battery life is acceptable, and the small form-factor is hard to beat. I have a few minor gripes:
1. The included stylus is necessarily small (skinny) and somewhat difficult to manipulate.
2. The included cradle leaves something to desire -- it does have a slot to charge an extra battery, but requires two hands and some concentration to place the PPC on the cradle, and the cradle plug assembly seems flimsy.
3. The included nylon case is fine, but the voice record button is located right where you grab the 4155 to remove it from the case, which sometimes leads to inadvertent recording.
4. The IR port is in a strange spot: the bottom corner of the unit.
5. Accessories are currently hard to find.
In all, these issues are quite minor, and IMO, the unit still deserves five stars given the competition.

Summary: Great Little Pocket PC
Review: After being a palm user of several years the only regret I have is that I didn't switch sooner. The wireless lan is amazing. Connecting to any wifi connection is a breeze. The vibrant color screen is an ease on the eyes after looking at a monochromatic screen for so long. Synching with my pc is simple and I like the fact that you can drag and drop files back and forth from the pocket pc and the desktop. Couldn't be happier!

Summary: Phenomenal Product
Review: A couple of days ago I decided to make the big leap from Palm (i.e. Handspring Visor) to PocketPC - and am I glad I did! Not only is there the obvious parallel of going from black to color, but the ease of synching ALL of my necessary files (especially Outlook) without having to go through mediator interfaces (e.g. DataViz and Chapura) is fantastic. All of the data comes through (not just truncated), and it is extremely legible. The third-party applications and data sources give it an enormous breath and functionality. But the deciding factor for this particular model was: no antenna to stick out, and yet both BlueTooth and Wi-Fi compatible. Have no doubt about purchasing this excellent productivity tool - you will not regret it!

Summary: Simply Outstanding
Review: iPAQ 4155 in my opinion is simply the best handheld device on the market right now. Combination of ideal size, full features and excellent performance is almost hard to believe. I've used it for about a month now and I am very satisfied. I use almost all of the advanced features including Bluetooth connectivity to my Sony T610 cell phone for remote internet access (this setup works quite well with T-Mobile data account), wi-fi networking at work and home, terminal services for control over other computers, data synchronization through wi-fi, VPN connectivity, etc etc. And of course, email and other related scheduling features work very well. All of this with a familiar Windows interface that is, I am happy to report, stable if not entirely intuitive. There are few relatively small gripes, like I wish the back cover of the unit was silver (aluminum) to match the front, the cradle could have been better designed no to put so much tension on the connector, more memory would have been nice (this, however, can be remedied quite easily by adding a non intrusive SD memory chip), the OS integration could be more stable (thankfully it is easy to recover from the rare freeze), the included case needs a belt clip, and such. However, these should not deter anyone form enjoying the fine product that 4155 is. You can use this thing as a mp3 player, use instant messenger, add a digital camera through the SDIO expansion slot, install software and games, read books, do work with email, excel, word, surf the net, connect to networks, and on and on... If you can imagine a miniature laptop pc, you are getting the picture. It is not however, an exact duplication of laptop or desktop capabilities. But it is a remarkably useful and powerful tool.
One word of advice: it takes patience and determination to make it do what you want it to do, particularly with more advanced features. But if you like this kind of stuff, then the capabilities are definitely there for you to use. If you're not technically savvy, then have someone knowledgeable help you set up everything you want and DO A BACK UP of it!!! Once you got that, you have one very powerful tool.
Verrrry Cool.
