My old laptop was giving me performance issues, had stuck keys on the keyboard and a few other issues. I was also sick of having to work around compatibility issues (the elantech touchpad and suspend/resume always gave me some problems), so I was looking into getting a new laptop. This time I wanted to get something I knew would work perfectly in linux, particularly ubuntu.
Finally got delivered yesterday, its pretty nice. 14.1 inch lemur ultra with i5-3210, 8gb ram and a hybrid hdd. Definitely the best linux experience I've ever had compatibility-wise, everything works perfectly out of the box.
I do wish there was a higher screen resolution available, but unity works well on the 720p screen. The battery life could also be better, only about 3.5-4 hours.
The performance and compatibility were the main draws for me though, and the machine delivers in spades there. Ubuntu/unity was extremely sluggish on my old laptop (intel i5-460m, 4gb ram, 640gb 5400rpm hdd). The dash was often slow/laggy to the point of being unusable, the intel ironlake graphics just couldn't handle it, the on a cold boot the whole system was always very unresponsive until it was used for a while due to the slow hdd. With this computer ubuntu just flies, it almost feels like a whole new OS. Boots in about 12 seconds to lightdm, and logs in almost instantly. Dash is always super responsive, no more laginess caused by the dash blur thanks to the ivybridge graphics. Its such a joy using unity on this machine compared to any of my past experiences.
Build quality is nothing exceptional, but seems pretty solid. Has a nice understated grey look. I quite like the touchpad that is completely integrated with the chassis. Its no ultrabook, but its pretty light/portable at 4.5 lbs.
