Connections, performance, and battery
Tablets, and hybrids that lean more toward the tablet side, typically suffer from a lack of ports and connections. The Miix 2 is no exception, offering only micro and mini versions of popular ports on the tablet itself. That means you'll have to travel with a pocketful of adapters and cables to make full use of the Miix 2. Fortunately, the keyboard dock includes a pair of full-size USB ports, which is handy, even if they're of the slower USB 2.0 variety.
Like most current Windows 8 tablets, the Miix 2 uses an Intel Atom processor. This low-power chip is designed to balance application performance with long battery life, while also running cool enough to work in small, sometimes fanless, systems. But in practical terms, even current Atom chips can feel pokey, depending on the task at hand. In systems with larger screens especially, the disconnect is more obvious, as you naturally expect those to act more like full-size laptops.
On the positive side, the Windows 8 tile interface, as well as most Windows 8 optimized apps, run very smoothly, even with an Atom chip. In hands-on use, the Miix 2 felt speedy most of the time, but also occasionally lags, which mirrors our experiences with other Atom-powered tablets and hybrids.
In our CNET Labs benchmark tests, the Miix 2 performed comparably to, or slower than, several other recent Windows 8 tablets, each of which has a similar Intel Atom chip (although not always the exact same model) and 2GB of RAM, but none with a screen as high-res as the Miix 2. In real-world terms, the performance differences were minor, and you're unlikely to notice much practical difference -- with the exception that one may be more forgiving of slowdown on smaller screens.
Battery life in the Miix 2 also matched or fell slightly behind other recent Windows 8 tablets, running for 7 hours and 22 minutes in our video playback battery drain test. Acer's new Iconia W4 ran more than 1 hour longer, but other Windows 8 tablets from Asus and Dell were better by only 10 to 20 minutes. Some hybrids include secondary batteries in their keyboard docks, but that's not the case here.
Lenovo's Miix 2 stands out from the Windows tablet crowd by offering a larger-than-usual screen, higher resolution, and a unique keyboard dock. It also costs more, at $599, which is closer to what you'd pay for a decent budget laptop, although the big 128GB SSD is no doubt responsible for some of the cost.
If the keyboard was easier to use and the CPU a little more powerful, the Miix 2 could be a handy portable productivity machine, but as it is, this will be relegated to being your backup device at best.
