Query: Pretty solid keyboard

I got this keyboard on a bet with someone at work. She bet me I would never go back if I tried an ergonomic keyboard. After a few weeks I bought one for my house. Coming from a standard keyboard this was pretty easy to learn and it has some nice extra keys like the "=" and "(" and ")" keys which is a big plus for those Excel formulas. Just do yourself a favor and do install the software. It makes a good keyboard really good. The only downside: no USB ports. It would be nice to have someone to plug in other peripherals.
