Hey ZombieBerry, I did come from the 9360 and before the 9780 ... Some new features like the Blackberry Device Analyzer are great, to monitor / run checks on the network, battery, device responsiveness and so on. It takes a moment to get used to the touchscreen
I've had some colleagues having issues with the defaul 7.0 OS - where the the berry was opening like a ghost menues, applications and so on ... with the "update" on the leaked 7.1 is better but definitely not yet 100 % - battery is better than the 9360 obviously - but the master of devices for us is still the 9780. Stable and reliable, still best battery ...
One great feature of the 7.1 is the WiFi Hotspot, so while travelling you can connect easily any devices via your berry. 7.1 is also out for the 9900 just recently installed on another device.. of course that will eat again the battery - which is a constant discussion...
