You may well already know, but it was also sold as the Toshiba E570, you may find more info under that name. I had one many years ago - nice little machine.
I bought one when they first came out. I liked having both SD and CF card slots. But didn't keep it long.
My big disappointment with it was the screen brightness. At max level it just wasn't as bright as the iPaqs or other pocketpcs I had owned. I even sent it back and got another. No difference. I had planned on getting the Thera, which was essentially the same thing in the phone edition. Glad I didn't.
I waited a while and when the Audiovox 4100 came out I got that instead. Screen brightness problem resolved.
Think I've owned most every pocketpc that ever came out one time or another. My all time favorite: iPaq HX4700. 4" screen, 640x480 resolution, built in wifi, bluetooth, switchable landscape/portrait screen, CF & SD slots…fast too. I actually still have a brand new one in the box somewhere…
