I'll admit that for the longest while now I've been using a Mac aluminum keyboard on my PC. I do it because I find the ultra low-profile keys on the keyboard have a fast, comfortable and quiet feel to them. I can type for hours on this keyboard without any discomfort and the quiet keys keep down the annoyance level too. Up until now, I've had a difficult time finding a keyboard designed exactly like this for the PC. When I saw a press release for the new Arctic K381 keyboard, something caught my eye - it looked nearly identical to my Mac keyboard, just it was natively designed for PC! I'm pretty anxious to check this keyboard out and see how well it will fare up to the Mac keyboard, just for half the price!
