Ranked in these QuestionsQuestion Ranking
Pro Topre switches at a good price
Pro Compact and portable footprint
If you love your keyboard enough to want to use it everywhere, it should be portable, especially if it's as expensive as this one is. The FC660C is very compact and easy to carry around.
Pro Solid construction
Heavier than the HHKB (Happy Hacking Keyboard).
Pro Topre switches are plate mounted
Topre switches aren't stand-alone switches, as in they are mounted to the plate. This means that the overall board is much stiffer (less flex) and less likely to have a key that feels bouncy.
Pro Quieter than Das keyboards
Pro Keys feel nice
This keyboard uses buckling spring key switches, the same used on the famous Model M keyboard, from IBM. This mechanism gives a nice feel to the keys.
Due to its good construction, this keyboard is very resistant.
Con Non standard key sizes
Non standard key sizes means your aftermarket keycap options are limited to non-modifiers. This issue also exists with virtually every other keyboard that utilises the Topre switch.
Con Can suffer from squeeky "plastic on plastic" rubbing with the case
Con Takes a lot of desk space
The Unicomp Classic is huge, so it takes a lot of space on one's workspace.
This keyboard doesn't look very aesthetically pleasant.
