Mechanical vs. Membrane Keyboards.
I own a mechanical keyboard for some time now, and I must say - in my opinion it is way better compared to my old membrane keyboard for both typing comfort and gaming performance, making it an excellent choice for programmers and gaming enthusiasts who spend hours at their computer.
Mechanical keyboards are gaining popularity as of late. While they were on the expensive side at first, you can buy (and assemble) one for under $100 today. Granted, you might need to get the keys and key caps to suit your needs in addition.
