for those wondering about performance improvements, as I mentioned in the thread for the 1.1 update, as often as not I find everything feels faster everytime I reboot. regardless of update. It just seems that after 4/5 days of heavy usage, things slow a little. and a full reboot makes things snappy again.
I doubt 1.1.1 has done any significant performance work.
(though would love to be found wrong)

here in the UK..still waiting ;-)
