I have a PalmOne LifeDrive.

Built in features include:
4 GB micro drive (Yes! 4 GB!)
Bluetooth
802.11b

Can open MS-Office documents (word, excel, powerpoint) and edit them without having to buy extra software. Listen to music, view pictures and videos.

I looked at the Nextel/Sprint Blackberry. However, $49/mo in addition to my cell and radio minutes was the deal killer for me.

I have been more than pleased with the LifeDrive.

Look on ebay. You should be able to find one new for around $275

Good luck,
Brent
