Has anyone else had serious issues using Microsoft peripherals? I purchased a Microsoft wireless keyboard and ergonomic mouse when I built my current Windows 8 machine, and have had nothing but trouble with both. The keyboard is at least functional, although it doesn't provide much insight to the amount of battery it has left. I'll be typing and suddenly it'll give out. It's usable, though. The mouse on the other hand has given me grief around the clock. Severe latency issues make it difficult to use, not just while playing games, but during basic usage such as browsing the web. I have to have two mice connected just in case this one throws me for a loop. It is a shame because I really like the feel of both the keyboard and the mouse. I just wish they worked. That said, I can't say I would ever recommend this keyboard to any of my friends.
