I've always liked these units I work in IT, and have imaged of hundreds of these E74XX,  when I saw one for $400 it caught my eye. Refurbished?? whatever was wrong with it has been corrected.I've had it for a couple months now and have had absolutely nothing go wrong. With the dual core i7 I rarely have have to wait for anything except maybe a heavy web page coming over the wire.I expected to pick up an 8 gig stick since there is an open slot to get a total of 16. But now that I've been working with it for a couple months, I don't think I need it. I think this unit retailed around $1,700 a couple years ago.Is it an E7490? no, but the $1300 in my pocket makes it a good personal laptop.You have to pay attention to Amazon's "descriptions" because you can't be sure what you're going to get.It claimed it was a 1376 by 768, turns out I got the full 1080 x 1920, they also stated that there was no camera. I have never seen one of units without a camera. It was there, just needed the Dell updates and the Windows 10 update. Also the licensing was something I had never seen before but it registered with Microsoft without a hitch.This was a great deal. The only possible catch would be if something does go wrong, I haven't tried, and I don't know if I have Dell support or not. Funny thing is it still shows it's under the original warranty for whoever bought it until June of next year.Don't think I'll need it. Forthose of you who agree with the infant mortality syndrome for electronics will understand what I mean when I say I'll be good for 3 to 5 years.
