Yes, X51 is pretty small for a desktop, but it is not designed to be a portable desktop. I love the idea of it though, and I wish Alienware produced this type of desktop.
Want a portable desktop? Check out the Raspberry Pi! Its the size of a credit card.
In the description on the site:
"can be used for many of the things that a desktop PC does, like spreadsheets, word-processing and games."
"like spreadsheets, word-processing and games."
"word-processing and games."
Really, now? The video card on that thing is practically non-existent! You'd be lucky to be able to run a YouTube video on that thing!
