My old devie was one Dell X 51V Pocket-Pc with Windows Mobile 5.0.My new device is a Nokia E62.I use it for professional and personal live, and love it!I use it to:- send and receive e-mails ( MS Exchange, Hotmail, Gmail, others ),- browse the web ( the screen is great, and you see the real sites ),- to write documents in meetings ( i use only one hand and can write with good speed ),- to talk with Messenger,- to listen music ( the sound is great ),- to play backgammon ( Fox Cunning ) and- to read a lot of documents like spreadcheets, PDFs and PPTs.To me it is the perfect professional and personal device!
