After a lot of debating, I bought the Acer C110TCi Tablet PC.
I'll definitely be blogging about my experiences. I looked at it again today in the store (for the second time) and decided I wanted it.
The Toshiba is nice, but the specs aren't as good, and the Acer's price/performance ratio is a lot better, especially since Toshiba hasn't even announced a new version yet. I've also talked to a lot of people (thanks, everyone) who have had good things to say about it.
I just hope the Acer's keyboard is big enough for my fingers. I was initially worried when I first realized how small it is, but I was pretty impressed after typing on it at the store, considering how small the keys really are. There's a slight curve to it, which might be why.
Talk about an ulta-portable though - that thing's tiny. And it's got some beef to it.
/me is keeping his fingers crossed.
