I purchased this EXACT same computer, the last time it was available on Woot! I was a little leery about it just having Intel graphics, but buying it new and customized added A LOT of money! I figured that if I got it and needed the "higher" version, that I could make back most of my money, since this laptop ONLY came out in July2013, and buy the full customized version.
I have to say that, so far, I haven't had a need for anything else! Windows 8.0 worked well and the 8.1 update makes it even better! The only thing that I wish it came with, was Windows Pro. However, you can still buy it for $99, if you want!
The mSata WiFi is "User" upgradable. So is the 2 Memory Sticks. There is room for 2 Hard Drives. However, it only comes with 1 Seagate 1TB drive, but it has the hard drive cable for the 2nd drive already. Lastly, you can upgrade the Optical Drive, if you want!
It's a great deal, for current hardware!
