I use the Blackberry Storm 9530 loaded with reQall and Evernote.
Why both? I use reQall for its voice note capture and transcription. reQall sends the messages to my Evernote account. My commute to work is lengthy and ideas germinate while I drive.
Evernote captures voice notes but doesn't convert them to text. It does have desktop programs one can install on Macs, Windows PCs, and SanDisk U3 flash drives. I use an iMac at work and a PC at home--I find that the Windows version works better. For Firefox users, they have Evernote Web Clipper add-on, as well.
