The point, briefly: I got a 17" 1GHz iMac G4. I got that computer for writing, so having a usable keyboard is a necessity. I'm weighing my options – buying a used keyboard for a replacement isn't just gross as you'll have to do the cleaning work, but also, it's a hit and miss if some keys technically work but not as efficiently as they once did, and the seller doesn't find it worth mentioning. The G4 probably doesn't work with the modern keyboards which are USB 2.0, but has anyone any experience or hearsay about alternative brand keyboards that would work with G4? If only for writing. But it would have to be USB 1.1 I guess. What's happening, in full: I got the iMac otherwise in an excellent condition, but the keyboard looked like it had never been cleaned; Gross, lots of dusty fluff between the keys. I removed all key caps and washed them in the dishwasher. Used cotton buds etc. to painstakingly clean the main body from all dust and lint. Came out sparkly clean, but I'm still having doubts: It looks clean but I'm having a lot of trouble typing efficiently. It seems to occasionally drop letters by not registering keystrokes and sometimes I may have to retype a word up to four times until I get it right. Back when I had that same keyboard model on my iMac G5, I didn't think that it produced a lot of typos or was otherwise hard to use. I'm starting to suspect that the previous user might've spilled something sticky onto the keyboard and now there's some old sugary goo on the touch pads, occasionally causing some keys to function erratically. I'm not sure if that's something that I could fix, really. Does anyone have experience of similar symptoms, and was there anything to be done? Do you think that these are symptoms of mistreated hardware, or an actual feature of the device?
