Is the a capacitive touch screen? How does the screen size compare to the iPad?
We bought a bunch at work and installed Cyanogenmod for one of our projects. It's the right size, and waaaay cheaper than an iPad. For $250, I'd recommend it for a general purpose (wifi-only) Android tablet. SSH is nice on it too.
Even though it's Android, the price is certainly right for an entry-level tablet.
I use mine to read recipes when I'm in the kitchen, and for single-purpose tasks like planning journeys using the Google Maps app. For these limited things, it's absolutely excellent.
Highly recommend CM7 running android 2.3.4
