My old computer, desktop, bigger than a briefcase, decided to start rebooting at random. Not good for those of us working from home. My brother (an IT guy) suggested this one, I got it and am just absolutely astounded. It's a little bigger than a paperback book and just sits there on my desk under my monitor. It's powerful, fast and quiet (way quieter than my last one, maybe it had issues longer than I suspected). It boots fast and I have no complaints.
