Well, my main machine is a Lenovo Y510p set up with additional monitor. Downside - hard drive died after about a year, upside - now has an SSD. Doesn’t meet the portability requirements very well though!
However, when said hard drive died I was just about to speak at a NetBeans conference. Ended up buying a refurbished 14" ThinkPad as a more portable and solid second device. Only about 18 months old, corporate so well looked after, and about a quarter of its original retail price. Doesn’t look sexy, though, but really why is looking nice a criteria? I would seriously suggest seeing what any local refurbishment companies have available - you might be pleasantly surprised. Sceptical I’d buy a new machine again.
