With my new comp, I got the Logitech Wireless Desktop MX5000, which has the MX1000 mouse and a decent keyboard, both wireless through Bluetooth. Well, it turns out that this set blows. Physically, both the mouse and the desktop are phenominal. But Bluetooth isn't. The mouse is VERY laggy (goes from barely acceptable to almost unbelievably bad.) I've (belatedly,) seen a number of user reviews complaining about the exact same thing. I tried playing HL2 with this set, and it was almost impossible. I kept running into walls, or off of ledges, because of the incredibly bad mouse lag. But I've still got the reciept, and I'll be (trying to,) return it, tomorrow.
My question is, should I go with the very similar MX3100, which uses more standard RF technology, and has no reports of lag, as far as I've seen. Really, are wireless mice/keyboards any good for gaming, or should I just stick with the corded variety?
