Same boat, here. And as an aside the best and fastest POS I ever used was a DOS-based system. I ;earned to key on the number pad because of it (now I need any external keyboard I use to have one). We actually got so good we could key up entire processes, invoices before the screens could update! This was pre-iPhone/touchscreens everywhere and I thought it looked old and outdated when I started. My appreciation grew after working with it, though.
