I bought the IdeaPad U310 6 months ago primarily due to the fact that Lenovo offered a good price (<$700 discounted from retail price of about $1.1K) for a 13 in ultrabook with 4GB RAM, i5 cpu. I like that the design is sleek and compact, and it is reasonably lightweight. I also like the pastel colors of the covers, and the white colored case. HOWEVER, there are 3 major flaws in this laptop, that in hindsight, had I paid more attention earlier, would probably have prompted me to return the item for a refund, and gotten myself a Dell or a Sony instead. 1) WIFI device is substandard -- it is slow to connect and not supported in some areas such as IBM offices. 2) Keyboard design did not seem to have undergone thoughtful human factors testing -- they made the keys way too soft and ultra sensitive even when I changed the settings in control panel. Return and Shift Keys on the right hand side have also been compressed to about half their sizes on standard keyboards to give way for the 4 up/down right/left arrow keys which is a redundancy because other keys on the right hand side provide the same navigation functions. These 2 issues cause a lot of grief specially when typing documents for touch typists since a very slight tap of even the side of the pinkie on the arrow key intended for the Shift key causes the cursor to jump elsewhere on the document messing up everything. One then has to constantly pay attention to they keyboard while typing and have to get used to backtracking and correcting when the cursor jumps, which happens often enough to be annoying. 3) Video Streaming is a PAIN -- it is slower, more pixelated, starts and stops and in some instances, can't even connect - NetFlix, You Tube, Amazon, Hulu, IMDB, Flash Player. And it has nothing to do with the OS - a friend has Windows on Dell and can stream videos excellently. It has nothing to do with the Internet Provider since I also stream videos on my Mac excellently. It has nothing to do with HW specs since my Mac has 4GB RAM and i5 CPU as well -- and I expected IdeaPad to perform just as well, but failed miserably. Because of these issues, I recommended that a friend NOT buy U310 or U410 regardless of the great price it offered.
