Sony Ericsson Aspen is the first mobile with Windows Mobile 6.5.3, the latest update to version 6.5 which is optimized for finger touch with various updates to the UI. It’s the first version of Windows Mobile to natively support capacitive touch displays ( HTC HD2 with Windows Mobile 6.5 has a capacitive display too though), finally bringing it up to date with competing mobile operating systems. Internet Explorer performance has also been updated, but I’ve seen most Windows Mobile users deeply in love with Skyfire.
