I wouldn't really say that the resolution would be too low for a decent browser, but I guess it depends on what you mean by decent. I have no issues with using my tiny cell phone's browser just to check small sites (like twitter for example). However, I can't say it would be worth waiting longer or buying a wifi dongle just for this. With the exception of my email, the only reason I use my phone's web browser is when I'm killing time and bored of the games on my phone, but with the Wiz I can't see that being the case!
If it was built in, I might use it, but it's far from anything I'm concerned with.
