I would say that compared to PDAs the N800 is good. It's far more scary when my T3 has a 'fatal reset' than anything that's happened on the N800 so far. The only times I've been worried was when it didn't want to boot, which for me was fixed by temporarily removing the internal SD card (and this problem is gone, for some reason), and a couple of days ago when it stopped in the boot process because of an upgrade to a buggy application (which was also resolved speedily). (In any case I quickly realized there's almost never any reason to ever turn it off. Was forced to once when the email app didn't want to start, but other than that I've only had to reboot because I was experimenting with the 3party Kismet application, which most certainly can't be blamed on the N800.)

No other serious problems (that is, problems that actually affected me, unlike when the PDA loses all its information and the like). Compared to a stable desktop computer the N800 is probably beta, compared to PDAs it's gamma.. PDAs are all beta, at best!

The N800 has the potential to deal with Flash videos (eg, YouTube) in a way that the 770 cannot.

We're due an OS update that greatly improves this aspect. And it can only get better.

I like my N800 and don't find it all that buggy. I think that buying a 770 now would be a bit foolish for most people -- the support and the fun and the momentum is going to be with the N800.

Thanks very much, everyone, for your advice!

I got put off buying a 770 based on the specs and reviews it got ... wanting to use a device like this mostly for websurfing myself ... got excited when reading raving reviews about the 800 and plunged in ... within days I was a very happy owner/websurfer of an 800. Considering it's size and limits, I'm amazed by what it can do. For web-surfing, performance is quite well, depending on the connection at hand. Collected wisdom (google) says using 770 for single-tasking like websurfing will work just fine.
