I updated to the new OS late last night and I found that the whole thing is more responsive. After resintalling some apps I saw most visible improvement in Gaim. Previously Gaim was unacceptably slow on my N800, so slow that inputing text would be causing severe delays. After the update I tried using MSN and Yahoo in Gaim and switching back and forth between Gaim and browser, RSS reader, etc. and it's A LOT faster. No delay in text input any more. For me Gaim is usable now!
