My next mouse?

I have used Microsoft mice for a while now. I like the tilt wheel and the forward and back buttons. I have been waiting for a worthy replacement for a couple weeks because my current mouse is getting tired. The leading contender so far has been the Logitech MX Revolution. I haven’t pulled the trigger yet because it just doesn’t feel nice enough to justify the $100 price tag. Today Microsoft announced a new version of the Microsoft Wireless Laser Mouse 7000. It has everything I need. Laser precision, rechargeable batteries with charger, bluetooth connectivity (so I don’t need a dongle), and a back button. It retails for about $70 and I am hoping to get it for around $50 once it hits Amazon. Now my only complaint is the fact that they didn’t change the name. They need to stop copying everything Apple does and naming new products the same thing is just silly and confusing for the customer.
