Windows 7 - Wireless Keyboard and Mouse question.

Hi,

I'm thinking to purchase those devices. Mainly for playing games like Dead Space 2, Warcraft 3 and Left 4 Dead + WoW.

A few questions:

1. Does wireless device affect sensitivity of crosshair alot?
2. In terms of durability, wired mouse and keyboard rarely break, at least for me. How about them?
3. I'm using multiple 2.4 ghz Wireless Access points here (diff. frequency tho), both indoor and outdoor, would it be wise to use Wireless keyboard + Mouse still?
4. Do you have any brands to recommend? I've got budget for like err... in dollars it would be 100 for both.

You won't get any interferance between multiple 2.4ghz devices. (Dispite wireless routers stating 5ghz stops conflict.. Interferance is impossible, I race remote control cars and there's often 100+ people all with 2.4ghz transmitters switched on at once)

Anywho. Only get a wireless mouse that states 0 latency. Othewise you will notice a delay. A more expensive wired mouse will far out perform a cheaper wireless mouse.

Only wireless gaming mouse I've experienced is my own, a saitek cyborg R.A.T 9. But at about £100 its going to be in the region of $160ish.

Also with cheaper wireless devices your restricted to use by battery charge, and if it is only supplied with one battery there will be times when your caught short. And if it takes AA batteries you'll be changing them weekly lol

Tsk 160 dollars is beyond what I expected lol. But I kinda knew it... somehow - as my experience with wireless camera was not different - the wireless version was more expensive than wired ones by alot.

Between the two, likely I'll be getting a mouse first after saving more money.

Thanks anyway.
