Definitely not as much of a fan of the T580 as much as I was of the T440s it replaced (still going, I only changed so I could give the T440s to someone else to replace their consumer ultrabook that predictably shat the bed and wasn't fixable). The T580 is much more plasticky, and it's also the last one since they ditched the 2.5 inch bay, and they still don't give you two drive slots (unless you get the 15p) except for sourcing one of about 2 models of SSD that fit the WLAN slot, which is getting harder and harder. And the suspend battery life is maybe 20% of what it used to be, but I could probably fix that if I wanted to. Anyway, it doesn't quite feel as amazing to me as the T440s was, and I know some people hate the '40 machines.
