It's a resistive touchscreen. Doesn't mean it sucks terribly, but you just gotta keep that in mind. If you think this'll feel like your android tablet, you will be disappointed.
VGA input? That's fine. I use VGA on my secondary monitor, and you can't tell the difference in normal operation.
Just note that once the Android version comes out, you can get a complete 10-inch artemis station for less than that.
