well I got the M15x about 2 years ago when I was still at uni (was a free replacement for my old m15x) and it was a very good laptop ran most thing very well but it was starting to feel its age so i got the m17x second hand for a very good price. and I was going to just stick the m15x on ebay and see what I got for it think most are selling for around £500-£600 but I just havent got around to it I've been using it as a second screan right now just to play videos and the web while I game. Also Have a macbook pro 13 as well lol.
