... can you use it as a phone?
If so, then great - it's a big-ish mobile phone.
If not, then it's a bigger and less easy-to-pocket version of my HTC Desire that I can't use to make calls on, meaning I'd have to carry 2 devices round with me for no net gain except a *slightly* bigger screen.
If the market is for use 'at home' as an alternative 'net browser - i've got a 17" laptop that boots in 45 seconds to a web browser, and a desktop machine that's about the same speed. That's before I get as far as the Wii hooked up to my telly if I want to check something on IMDB quickly. Why would I use this? ESPECIALLY as i've always got my phone in my pocket, which is likely to be quicker to get to than anything else.
I suspect the only market for this will be people who have a bog-standard 'only makes calls' phone. But then, if they've only got one of those phones, odds are they don't give a toss about mobile internet...
Just like the iPad, I struggle to see the point.
