What's the deal with using a cheap, non-apple bluetooth mouse?

[wicky]

I usually use a Wacom Intuos pad with my MacBook Pro, but want to buy a cheap Bluetooth mouse with scroll wheel for browsing and such. I'm loathed to drop $70 on a Apple Magic Mouse.

Many of the mice (mouses?) I've seen come with a Bluetooth USB dongle.... this confuses me. Is it necessary, and if so why? I only have 2 USB ports so don't want to surrender one for basic mouse connectivity. Is there a cheap Bluetooth mouse that will simply connect to the MacBook's internal bluetooth?

Thanks

Dongles are often included, because many mice will be purchased for non-Mac computers, which won't necessarily have built-in Bluetooth.
Even if the mouse comes with its own USB dongle, you already have bluetooth built-in - so for you, the additional dongle is not necessary.
Quite a few cheap BT mice: http://www.newegg.com/Product/Produ... 600009584&IsNodeId=1&name=Bluetooth Wireless
I lean toward Logitech: http://www.newegg.com/Product/Produ...3 50001080 600009584&IsNodeId=1&name=Logitech
