Hi all.
i like to play cs lately (esp. on end2007 holiday)
i have some difficulties playing in my desktop which have Microsoft Wireless Optical 4000. and also another Microsoft wireless optical 2.

@fantagero:
avoid microsoft's wireless desktop if u want to game.
but go for it if you want comfort...

so i have 2 exact and identical mouse (except colour) but i feel its heavy to move around. so i remove 1 AA battery and it works better.
but still, its not so good for FPS gaming... my std optical mouse works better.

but recently i got so called creative gaming mouse, HD7500,
because its only priced at SGD8 this month (RM20).
very comfortable at its price, but havnt ask my friends about it...
Creative HD7500

just be aware that almost all MS wireless keyboard will terminate keys pressed randomly after some time holding it. means, for mine, when i play racing games.., accelerate.... few seconds suddenly no response while holding the key. so must re-press. when i read complains from people in google. they say this is very normal to microsoft wireless keyboard. and that's why gaming is better with wired system... not sure bout logi though...

lets wait from some people opinion here...
