mechanical switches are no obsolete and extremely lag intensive.
Bloody has a IR sensor keyboard out that has .02ms compared to mechanical switches at 18-30ms and also has a 1.2mm activation rather than mechanicals 2.2mm
i don't really like it's poor design, but it's compact, multi colored, orange wasd and 1st P-shooter action keys named B720 Light Strike, it's priced outrageously for the features at $180
the mouse they offer has the same IR sensor switches with the same ms timings, is alot better designed even the ZL50 Sniper Laser but it's priced better at $80 (still a bit steep in my book for it's functionality and design)
don't have one to try or test with their software but Computer Power User has a decent article posted about it this month.
