Here at Smart Imports, we have been using the HHKB Pro2 for a number of years, but recently got this model of Realforce for one of our desktops. We are VERY happy with it. We still have my HHKB Pro2 for one of the laptops when I'm working away from home though. I'll quote from my HHKB Pro2 listing, as the same applies to this keyboard: "Before I found the HHKB Pro2 I was buring through keyboards about every six months to a year. Normal keyboards would get sticky and unresponsive after less than six months and nicer $60 mechanical keyboards would start slowing down after less than a year. That's why I would say buying a $300 keyboard is actually a savings if you need to type a lot like I do. You won't buy another keyboard for YEARS. "
