It doesn't have a contacts picture view or the second utility row in the standby screen but has everything else including (an optional) taskviewer and recently used list, whilst being more flexible and offers more functionality including :
Speed dials, speed contacts/sms/mms/email, links to files, folders, apps, weblinks and documents all with hot keys and in definable folders.
Still it's all personal preference....
I haven't checked out GDesk for a while - it looked a bit basic compared to Tracker whne I was in the market....
Know your limits - and double them!
