So wait, it supports a processor that was introduced 7 years ago in November 2008, has room for the minimum about of RAM I'd expect on a modern PC, and well under half what I could have installed on my desktop 3 years ago, only room for two hard drives, and a 4k screen? it really doesn't sound that great.
You try lugging that desktop around in a bag and we'll see how that works out for you. Hint: laptops aren't desktops for a reason. Also, the M3800 sports Haswell CPUs (another hint! i7 indicates relative strength within a series, it's not the series itself), which were definitely not introduced 7 years ago. Better luck next time.
