I recently switched away from AVG as well, but I tried Avast instead. No nag screens anywhere, and it's easy to get a very light install without any extras. No performance issues that I've noticed.

Yes it is - the Z22's screen is similar to the Zire 31's, which I can say from personal experience is quite nice, even though not hi-res like the higher level Palms. And for the record, I'm a bit miffed about this as I bought a Zire 31 not two weeks ago, and I'd switch for a Z22 in a heartbeat. The only downside to the Z22, in comparison to the Zire 31, is the lack of an SD slot for expansion (which means no MP3s for you silly people buying a PDA for music). I personally wouldn't use more than the 20+ megs available in the Z22 but that's a personal choice.
