Wi-Fi Networing News got its hands on the Nokia 770 and just posted a write-up. The short version: “agonizingly slow”

A bit more detail:

There was plenty of discussion … about the slowness. It’s hard to get past that aspect because it made the whole experience so not pleasant. In addition to slow response time, downloading Web pages was also quite slow. The 770 comes with built-in Wi-Fi so should have been fast but it was a lot like using 3G on a cell phone or PDA.

Hopefully they’ll be able to fix that in software before the launch. If that fails, the only choices are adding more RAM (which adds cost and reduces battery life) or scrapping everything and starting over with a faster CPU. I’d really like to see this little thing succeed, even though I don’t know what I’d ever use it for.
