I would not hesitate to recommend the Unicomp Spacesaver M to Macintosh users used to an original IBM Model M, and I am admittedly a tough customer. I wish that Unicomp would update their website, packaging, logo, and keyboard graphics, but none of this really matters as your fingers press the keys. If any keyboard is worth $100, it is the Unicomp Spacesaver M!

Review: Das Keyboard Model S for Mac (and Why I’m Sending It Back)
Make no mistake, the Das Keyboard Model S for Mac is a whole class better than the plastic junk most people use, and the snappy Cherry MX blue key switches are more rewarding than any scissor or membrane keyboard out there, but this is no IBM Model M, so buckling spring fans should look elsewhere.
