I played Evercrack on a laptop for years. Wasn’t so bad.
I played WoW on a laptop in the 2007-2008 timeframe too, and it wasn't bad either. But over the past 2-3 years my eyes have gotten a lot worse, and now laptops are pretty unusable. Mobile devices with those tiny little screens are out of the question - I hate them.
A nice big 24" or larger monitor is where it's at now - regardless of what kind of box it is - a laptop, mini tower, full tower, or a small potted/soldered/throwaway micro-box of the future. As long as I can plug in a big screen monitor to a DVI/HDMI port I'm happy.
Back in the 90's and early 2K's I upgraded [AMD] processors on a couple of motherboards - but no more. Now it's out with the old box & in with the new (now with Intel CPUs), and I don't open the box for anything more than upgrading graphics cards & power supplies to fuel them. Unsocketed motherboards are a don't care for me at this point. And I do wonder what AMD is going to do about this, and if it's a new opportunity for them. I haven't bought an AMD processor in 7 or 8 years now.
