I loved my P800 and P910 but Sony Ericsson followed those with the P990 which was underpowered for the bloated mess that UIQ 3 on top of Symbian 9 was. I much preferred UIQ 2 to UIQ v3. v3 had stupid animations and annoying pauses in the UI. SE managed to kill UIQ by launching it on woefully bad hardware. IIRC the next smartphones they released ran Windows Mobile. That's how much faith they had still in Symbian. Yet in Nokia S60 seemed to be some kind of cult that had to be fed by sacrificing all common sense on it.
