Bluetooth Mouse - does it worth?

Hi,

I have a laptop with built in bluetooth (Vaio FW) - 2.0 + EDR and I want to buy a bluetooth mouse, but I am not sure I this is the best option I can choose; maybe an ordinary wireless mouse (not BT) is a better option, but I don't know to waste one of the 3 USB ports with a dongle.
I am wondering that if I have a bluetooth mouse, will I be then able to connect my phone to the laptop (via bluetooth) or some BT headphones or any other bluetooth device (I also want to buy some bluetooth speakers for my laptop). Will then be the mouse movement as smooth as before while listening to music or transfering files via bluetooth?

I have done a test. I connected two phones to my laptop (Nokia N97 and Nokia 6500c), bot via bluetooth, at the same time. I used the laptop as it was the handsfree for one of the phone (phone's sound was heard in laptop's speakers) and with the other phone I was transfering some files (from the pc to the phone). The speed of the file transfer was three time slower when using the laptop as speakers for the other phone than using only one bluetooth connection (one phone with file transfer).
So, the more devices are connected to the laptop, the slower the speed (of one, or more of the devices) of the connection is.
I am wondering if the bluetooth speed cope with both a mouse and a headphones/bluetooth speakers (which I intend to buy).

Thanks in advance.

 

Bluetooth can connect multiple devices simultaneously. In my experience, connecting a phone or headset does not affect the mouse motion.
