My trusty old Asus laptop is starting to get a bit creaky, plus it weighs around 2.5kg (probably. It's hefty at least). So i'm looking to pickup a new laptop this year, and an Ultrabook appeals to my tastes and sensibilites. The Lenovo Carbon X1 (14") and the Samsung Series 9 (15") both look generally perfect.
Is anyone out there doing development on an ultrabook/hybrid (hybrid being something like the surface pro or the Lenovo Carbon touch). Have you found any issues with development on these machines over the use of a standard laptop that doesn't have limitations of soldered ram and such?
