I went with the m17x. I would love to have spent money to build my own rig and deck things out, but I had to make the call. In the end, I have to have something portable. I need the ability to take my system to many placed, from family's houses, to road trips, to clients locations (for my IT work), and so portability is a must. I have my tablet and phone, but my tech world is laptop centered. Not to mention I do a lot of gaming, and keep tons and tons of rulebooks and everything on my system.
