Been running it for a few days now. Upgraded from .150.
.162 seems to be equally good... pretty stable, decent memory management, etc. etc. Can't really say "better" as I honestly don't know, but I'm sure it must be.
Haven't done any browser speed racing tests yet, but am finding there are still some glitches with the browser. Specifically, if I browse a website, then close to home screen by hitting the end key (don't actually do a full close on the browser) and then do something like check email and reply to emails, I get the hour glass coming up within the email app (device slows up accordingly). I guess the web browser is still running in the background (even though the page I was visiting is fully loaded) and seems to be consuming a lot of memory or something. If I go back and full close the browser, then it speeds up again.
Going back to New York would be a good test.
Other than that, so far so good. Will update if I find anything.
