Need a wireless mouse

[indianarchie]

I am looking for a wireless mouse for daily use with laptop and desktop.
Requirements:

[*]Must have a nano receiver
[*]Needs a long battery life - I will use this for 8-10 hours daily, so any idea on what kind of life I can realistically expect?
[*]Must run on AAA batteries only (since I have a set of rechargeable AAAs)
[*]Must be comfortable to use for extended periods
[*]Nothing too expensive
[/list]I want to avoid desi brands like iball. Currently using a Microsoft Arc Touch mouse, definitely need something more comfortable and less expensive than that. Something around 600-1200 bucks would be the sweet spot.
Another good feature would be if a single nano receiver can pair up with both mouse and keyboard. I am not looking for a set/keyboard at present, but it might be nice if I want to in future.
Any recommendations?

I thought I would post an update.
I finally bought an HP x4000 mouse from Snapdeal for Rs. 969. It's wireless, laser, claims a 30-month battery life(!), and has a multi-device nano receiver.
The only downsides for me are, it uses AA batteries instead of AAAs, and it's slightly small. I can live with these.
