Summary: Battery replacement causes complete data loss
Review: I was happy with this PDA until recently. Now changing battery always causes data loss. Manual says to replace battery within 1 mintue. I replace it instantly (5 seconds - I timed it , have to do jugglery!). Even then total data loss and have to resync everytime which is a big headache. Someone suggested having to supply the battery holder with voltage thru another battery pack while changing the battery. While that would work, that is a clumsy workaround and you have to be techie kinds. Even though I am techie kind, I do not like that approach. Palm should have thought about this reliability issue with this model.

Summary: Just Ok
Review: Even for the cheap price, this is not worth the hassle. The batteries die quickly without any warning, thus losing any information loaded into it before getting a chance to hot sync with your PC. There are many other used products on the market a lot better than this one. Save your money and future headaches!

Review: I won the m100 from Palm back in 2001. It's served me well. I've dropped it, banged it, and a few things in between and it still works. I've only had to replace the flip cover. I've spent probably $24 on batteries over the past 3 years for the device. I've gotten the full use out of a free product. For the person new to palm who doesn't need all the bells and whistles this is the one for you!

Summary: Great Product!!!
Review: Palm M100 dies every 7 days. The batteries just don't last - even if I don't use it. It usually ends up being dead and all info lost about every week. I have an older model Palm III which is similar, but the batteries last a few months before they die.constant hotsync and battery replacement is a pain. try to get a Palm III instead.

Review: I have the 105 w/8mb memory but it's the same pda otherwise. The good stuff is the size and easy to carry around. The bad stuff is that you must use a serial port (the usb kit rarely works and is major trouble). My pda has to reset whenever you change the batteries so I must do this next to my computer to re-synch. If you can get it for cheap, it does the basic job. Make sure your pc has a serial port to sync, many newer pc's do not. Also, downloading software updates from Palm is a crapshoot since many dll's did not download. Support via email does not resolve problems.
