I've only done it once on the way to Melbourne because I needed to send a PM. It was fast reading it in simple text then it asked me if i wanted to switch to HTML, which I said OK. It was a bit laborious scrolling round the screen, I wanted to plug in a monitor but everything was there. I got a Nokia N95 BTW which has a decent screen but not sure how it compares to others.
The only problem with that one incident of ORG dose whilst in transit is that I'm not on any fancy extras plan for web use so I got charged 15-20 dollars for that little browse

Oh yeah, I should say I looked up more than my PM's, I did look at all the unread threads, viewed pics etc and was on for an hour or so
