Summary: No complaints
Review: I have used the 4570C intensively for over a year and have had no problems whatsoever. Why there are so many complaints about the software is a mystery to me. It takes ten minutes to install and off you go. The only problem I've encountered is that when you scan a photo from a book but have scanner set to slides (which I also scan), you get lots of horizontal lines until you fix the problem. The troubleshooting technique in manual resolves this issue, irksome though it may be, in just a few minutes. My picture files take up about 14 gigabytes on my hard drive so you know I have been using the 4570 intensively. I would buy another one for my lab but Best Buy quit selling them.

Summary: This scanner works GREAT
Review: I hooked up my HP 4570C in 5 minutes and it scans in a few seconds flat. I scanned to my printer also, in color, in just a few seconds. I have no trouble editing pics. I am running Windows XP on a Pentium 4 with 512 mb RAM. I would recommend to anyone, I found it simple and fast, excellent quality.

Review: I know that others don't like this scanner. But I have found it easy to use. I can change the resolution, color, contrast, etc. before importing it into Adobe Photoshop, HP Photoprinting, Adobde Illustrator, and Corel Photo with no problems.
I also love the fact that I can scan my negatives and go on from there as if it were a regular photo on the glass.

Summary: Truly terrible software undermines decent hardware
Review: I've had the same experiences that many others report. My scanner cosst, well, let's say multiply the number of your fingers and toes by two. Even at that prc-point, this product is a disaster.The good news: The hardware is solid. You can return it easily. HP support is ok but bureaucratic, given that they have to work within the limits of the product. The bad news: I've NEVER seen such bad software (and I've used a lot). As others have noted: It's slow, very buggy, and gets quite confused about what's happening with the scanner. And there are too many little apps--in all, lots of complexity and little sophistication. But the biggest problem is that its design completely ignores the variety of workflows you might have for scanning different docs in different contexts. Rather than making scanning efficient, you might begin to suspect that HP was intentionally trying to waste your time. Why else would they release such software? This is a plea to HP: Please, please give your software development much higher priority. Look at the Apple iLife apps for usability experience ideas (I say this even though I'm using Windows). If you need to, divert money from your advertising to software development. It'll be money well spent towards keeping your reputation alive. Specific example problems: Scan settings appear to be arbitrarily remembered by the various programs. Data transfer among the multiple programs is at best unreliable--after doing multiple hi-res slide scans to save time I've had the terrible "HP Director" appplication just crash before handing off the files to the "HP Photo & Imaging Gallery". Poof--all the scans are lost (I can't even find the temp files...and of course where they're stored isn't documented). Resetting default scan values doesn't seem to take. The "HP Scanning" application (there are too many small apps installed) seems to constantly lose track of whether the lamp's warmed up or not--even after it's been on for an hour! The "HP Photo & Imaging Gallery" is incredibly slow--it seems to constantly and needlessly recreate thumbnails of large scan files. (It's slow using version 2.0 of the scanner software on a 1GHz XP machine.) Frequently it'll display two thumbnails for the same file, or no thumbnail for a file you just scanned. And it freezes. And the selection of tools is uneven: zoom but no hand to move around images (scroll bars only). And, and, ... . HP, please partner up with a company that has stable existing software, such as ACDSee's image viewer. I can't imagine what it's like working at HP these days handling tech support for this product. My sympathies to HP tech support.

Summary: read below
Review: Naturally, the scanner creates good quality images. However, on some images there is an inner, lighter frame which, as I figured out, is the top portion of the flatbed being somehow reflected. I'm trying to find a dark book or something like that to scan those images and for the money I paid I should NOT be worried about this crap. Second, the software is idiotic: made by idiots with idiots in mind, you know one of those that assume you're 10 and just got your first computer ever.

Summary: OK scanner, good price, but the software makes it unusable
Review: Nice scanner, good front panel buttons, easy to set up and install. But the software handcuffs it. In an effort to make things easy for the naive user, HP has brain damaged it beyond repair. For example - once you preview and then do a final scan, it throws you out of the preview screen and into the picture viewer. If you want to redo the scan, or scan a different part of the image, you have to get out of the viewer, back to the scanner, do another preview ... see the problem? On quality - all I can say from a brief trial is that the 2400 dpi scan of negatives was noticeably less sharp than a 2400 dpi scan I sent out to Kodak. I'm told that the higher end and older HP scanners - the 5400 and 7400 series - come with less inflexible software. This one is going back.

Summary: Buy another scanner
Review: Scanning quality is fine but software is based on the premise that you are a first-time windows user and do not know what a pixel is. It practically renders scanner unusable. Wish I could return it.

Summary: Avoid HP's Horrible Software
Review: The hardware is adequate for the price, with good, vibrant color. But the software is so terribly written, with a clunky, bizarre user interface, that it's a huge pain to get anything done. And woe betide you if you ever need to scan more than one slide at a time with the included transparency adapter. For each slide you must laboriously tell the import software to use the adapter, which you cannot do until it has made a useless preview scan with the flatbed. Avoid this product like the plague. Shame on HP!
