Well I'm in the market for a mechanical keyboard that is Mac specific. I've thought about getting an old Extended keyboard, but they're getting harder to find in good condition for a decent price on eBay. And I thought about an old IBM Model M "buckling spring" keyboard, but again, I want the command keys (yes I know I could just remap the keyboard, but it's not the same). So I think I've narrowed it down to the Matias Tactile Pro 4 and the Das Keyboard Professional Model S for Mac. Does anyone here have any experience with either of these? I'd love some feedback to help me with my decision! I'm mostly torn between whether I should get the Matias' Alps switches or the Cherry MX Blues in the Das. I've also heard that there's been build quality issues in the past with the Tactile (but it looks nicer), while the Das seems to be built like a tank (but it's as ugly as one too ). Please help! Also speak out about any Mac mechanical keyboards if I have forgot about any. Thanks in advance!
