Question: Can I use CD/DVD?
Document: Although perhaps not as hi-def as a full retina display, it is much more than DVD quality and plenty big enough. It provides a crisp image throughout and didn't display any tendencies towards motion tracking or blurring when I played a DVD.The case is perhaps the most attractive part of the machine, but it also functions superbly as a stiff, light and durable frame. The little XPS is significantly stronger than any other laptop I have used, including my wife's MacBook Pro17.
Very robust construction and light weight. Keyboard is large, illuminated and agreeable to use.
I wonder if Dell has used  rejects or substandard parts & bumped it off as a high end corporate model.Will strongly recommend not to go for this laptop - I think Toshiba Protege series offer far greater reliability. I am seriously considering reverting to my Toshiba Protege machines which have served me relaibly for the last 5 years & offer equally stunning looks & low weight.Though not specifically stated, this machine does not have a Lan port & hence one has to only use wifi.
So fast you can't believe it. Be sure to update all the drivers. Have yet to run the battery all the way out after 6 1/2 hr battery use. Love the keyboard-lit and great tactile response..The 2d generation Core I7 is lightening fast. Saved nearly $400.00 at Amazon. It's the first generation of this model, but great quality touches and responsiveness. If Amazon has any of these Dell XPS 13's left at that price-snap them up!
The only problem I found is that only has 2 USB ports, you have to buy many adapters for different functions.
I have been running Ubuntu for the past two years because I couldnt stand how slow my old laptop with Windows XP had become.
Small, light, fast, great finishing and not that pricy. I think Dell is still one the best PC makers, and this product honors their tradition
I have purchased dozens of Dell computers both for home and business purposes and have been quite happy with the quality most of the time. However, now I'm having a nightmare with a XPS 13 that is only 3 months old.
I bought this DELL XPE13 recently. It works well till now. But I don't know how could I get a formal invoice from dell or amazon? I can only see the informal print version of that. Does anyone has the same question? Thanks.
I bought this early on (March, 2012) and REALLY wanted to love it. Weight and form factor are EXCELLENT.Sadly, it's just not all that. Screen was so so. Speed felt sluggish, even coming out of sleep wasn't great. It had a wonky track pad as well.It went back. My search for a next generation laptop continues.
Answer: No you can't. It's physically too thin, which is the idea to begin with.
