Yesterday, palmOne announced the Treo 650. Here's a link to a video and an early review of the new device.

Looks like palmOne kept the form factor the same as the Treo 600. Some of the changes include:

• 320x320 high-res screen
• Removable battery
• Faster processor
• Built-in MP3 player
• Improved camera (mirror for self-portraits; captures video; works in low light)
• Supports IMAP or POP email
• Bluetooth
