What put me off was using them a few years ago. All the computers at work were Dell and they couldn't cope with intensive design stuff. In the end I was given a wedge of money and was told to build or buy myself a PC (had to be PC) and I built a monster! I am sure they're OK for knocking out emails, MS Office and so on but try working on a 8GB+ image several meters across and watch them die. So unless Dell have pulled up their socks in the last three years then I wouldn't touch them. Really don't like them. Getting phone calls on my day off because the email server has gone down, or the till computer, etc. etc.
