Bluetooth mouse/keyboard ... 2.0 or 1.0?

[trend]

I am looking to geta bluetooth mouse, and I only see MS providing bluetooth 2.0 mouse/keyboard combo... So my question is:

Is bluetooth 2.0 that much better? or just going with the bluetooth 1.0 mouse from MS be fine?

My main concerns are.. My MS wireless (RF) mouse has a LONG battery life.. where my logitech wireless has 1/2 the battery life.. and since i don't have my ms one anymore.. i need to get another ms..

Also, my logitech wireless keyboard had a lag on it, and i am wondering if the bluetooth will have similiar..

I do have a MS bluetooth mouse, i like it, the only problem is I can never power off the mouse, so it is kind of drain. If i use my computer everday for 2-3hrs a day. I need a 2 AA battery every 2 months. Hope this helps

oh wow... maybe i was getting awesome battery life out of my old ms mouse... I use my ocmputer 6+ hours a day.. and thought i was getting a couple months battery life from my mouse

well, getting bt 2.0 device would be better in the long run. i'd say get the 2.0 device if cost isn't much different
