Office Mobile now includes also One Note Mobile application - apart from Word Mobile, Excel Mobile and PowerPoint Mobile, one new application is available - it can record voice notes and drawings and textual notes
Internet Explorer now has function "Zoom Out" what enables page-overview mode and better overall navigation through web pages
Windows Mobile 6.1 still is based on Windows CE 5.2 so no upgrade to Windows CE 6.0
SMS chat view mode is available so SMS messages can appear in threaded-way - more comfortable to follow SMS conversations
instead of "Settings / Memory / Running Programs" now a Task Manager is available with possibility to set settings of executed threads/processes like CPU (indication of dual-core Windows Mobile devices?) and memory
new menu item "Managed Programs"
the much expected improvements in usage for finger based navigation - are nowhere to be found! (apparently users will need to wait till 2009 for Windows Mobile 7 to get them)
