Well, I have an Atigo T but I had been looking for a table for a long time, and among the alternatives that I considered was buying a WinCE-based GPS because there's a package called MioPocket that is supposed to install the missing CE components so that any Windows CE compatible applicacion can run. At least Mobipocket Reader is confirmed to run and even included, which was what I was interested the most. Guess it's worth a try.

What is MioPocket?
MioPocket is a frontend for Windows CE-based devices, mainly GPS navigation devices. It is an installable package of programs, scripts, registry files and skins to "unlock" PNA/GPS devices and allow them to be used for far more than just navigation (ex. for music, movies, appointments, multiple navigation apps, etc.), like PDAs. Nearly all GPS devices use Windows CE as the core operating system, just as Pocket PCs do, but they usually try to keep you from accessing the operating system so that you can't mess anything up. MioPocket gets around that to open up a world of functionality to what is, ordinarily, a very limited device. MioPocket is the most-packed and most-fully-featured unlock for PNAs available and is free and legal to use, as it consists 100% of freely-distributable content. What MioPocket is not is a replacement for MioMap, Mobile Navigator or any other OEM navigation software. It is just a frontend from which you may launch your device's navigation software or other navigation software that you've purchased.
What types of programs does MioPocket come with?
MioPocket comes with just about everything that you might want: three media players (video and audio, nearly all popular formats, including MP3, WMA, OGG, MP4, H.264, WMV, MOV, DivX and XviD), three e-book readers, multiple dictionaries (inc. English to 5 languages), dozens of games, two image viewers, two paint programs, MS Office document viewers, text editors, handwritten note-taking apps, a MioMap route manager, four general GPS plotting/mapping apps, three different appointments/tasks apps, a contacts app, a calculator, a unit converter, registry editors, task manager/switchers, file managers, an alarm clock and more (all free/shareware). See the Readme file for a full list. Note: MioPocket does not come with MioMap, iGo, Garmin, TomTom or any other commercial navigation software. Icons and scripts are included for them, but not the programs, themselves (since they are not free).
Which devices does MioPocket run on?
Technically, MioPocket should run on any Windows CE-based device.
Please do post your experience, I'm interested to know how useful WinCE 5.0 can become.
