I've had no experience of wireless keyboards, but I've been through a fair few wireless mice, the best by far being the Logitech G7. It's the best wireless mouse I've tried to date for gaming.
Yeah it may lack the silly number of buttons that other wired equivalents boast, but it's rock solid stable, can be used at 25 meters or more (I've actually tried this myself) and the build quality and durability is outstanding. The instant battery "reload" feature is amazing, it's *fun* when your battery dies because you can switch the dead one with the one that's been charging in the single USB port powered charger.
The charger has a USB pass-through attached for you to use the wireless receiver with just one USB port, no messing around with docking stations (which is something I really hate about other wireless mice).
Spec-wise, you're looking at 2000dpi (selectable, 400, 800, 2000dpi by default but the software lets you change to use up to 5 levels and different values like 1600dpi etc), not the best in today's market but definately ample for most uses. The battery lasts around 8-12 hours in my experience, but that's 8-12 hours of solid use and there's no "sleep" feature, which means the mouse is always ready to go the instant you move it but obviously this eats the power quickly, I can see why they made the battery so easy to switch out.
But yeah, I can't fault the G7, I won't be changing it any time soon, not unless Logitech release an even better version.
