Introduction and Specifications
As the Windows-based competitor to Apple's popular MacBook Air, the ultrabook category has been reasonably well-received. Intel created the term "ultrabook" last year and stirred up plenty of buzz about it at CES this January, promising systems that would be powerful (compared to netbooks) and svelte (compared to notebooks). You'll turn heads if you fire one up at your local coffee shop, and you won't need to quietly suffer through sluggish performance to look so good.
One area that has been a challenge for manufacturers is the ultrabook's price point. Intel's $1,000 goal (not to mention their recent Ivy Bridge ULT-based $799 target) has been hard to hit, given all the pricey tech that goes into making these slim systems sing. Most have come in at well over the $1K mark – until recently. That brings us to the
For manufacturers, there's always some risk to sending us anything less than the top of the line model. Generally speaking, a computer makers wants its best system to be reviewed. That's a reasonable approach, and it means that because so many review systems have the best tech that their lines carry, a lower-priced model is likely to look a little pale by comparison in performance analysis. That's something worth keeping in mind as we dig into the U310: the ultrabooks you've seen recently may have more power, but they're also much more expensive. Whether the U310 strikes a solid price-for-performance balance is what we're setting out to learn. Can an $800 ultrabook take you through a day of hard work and a little play?

Lenovo sent us a U310 with an Intel Core i5-3317U processor, which runs at 1.7GHz and can reach 2.6GHz with Turbo Boost and HD 4000 graphics. The ultrabook includes a reasonable amount of DDR3 1600MHz memory at 4GB, but it's all on a single DIMM. We noticed the single-channel memory when reviewing the Lenovo IdeaPad U300s and we were surprised that Lenovo didn't go for the extra performance of dual-channel memory at the time. It looks as though Lenovo hasn't changed its game plan here.
SSD cache. The combo is designed to approximate SSD speeds and helps the U310 provide a faster boot-up time (about 26 seconds in our test) along with faster overall speeds than you'll see from a standard hard drive. The combo isn't likely to be quite as fast as a dedicated SSD, but it's a way to balance price and performance, which is what this ultrabook is all about.
The U310 doesn't have space for an optical drive, but it does have an SD card reader, which is handy of course. It also has a LAN port and built-in Wi-Fi, as well as Bluetooth. An HDMI port, three USB ports (two of which are USB3.0), a 720p web cam, and standard mic/headphone ports round out the package.
