Mine is on 25d 16h 56m now, still very responsive
I'm thinking about reflashing, because it got some issues, disregarding uptime.

Animations stutter a bit, but that's not very important, the thing that does bother me, is that some SMS's stay on 'pending', even if they are sent. Some of them also don't show up after opening the conversation again, including the recieved messages in between. After a reboot I get all those recieved messages at once :P
