Also the storage space. Tablets and ultrabooks still don't give you enough space if you need to install a lot of development software, database servers, etc. Oh, and if you need to develop in more than one OS, then a tablet isn't going to cut it, and the 128/256GB SSD in an ultrabook is a pretty tight squeeze for dual boot. Those factors, the RAM and the back pain are the reasons I stick with larger devices for now. I do have my beady eye on the forthcoming Asus U500 though.
