Conclusion: But if you need the convenience of a part-time, pen-enabled tablet and an 11.6-inch ultrabook, with close to all-day battery life and exceptional input devices, then the Helix is the one for you. On its terms, it's one of the most successful convertibles we've seen.
Pros: Comfortable keyboard, Good battery life, when attached to keyboard base, Touch pad is tuned for Windows 8, Supports touch-screen and pen-based input
Cons: Expensive, No SD card slot, 3rd Generation, not "Haswell," processor, Awkward vent location
Conclusion: The Lenovo ThinkPad Helix is a versatile, powerful and well built transformer tablet-Ultrabook. It has the computing performance to handle Adobe Photoshop, software development, RAW photo editing and more and the Wacom digitizer with pen sets it apart from touch-only tablets. We adore the excellent keyboard and solid touchpad, as well as the secondary battery in the dock. We wish it had a backlit keyboard, but that's not a deal breaker.
Pros: Good performance, sharp full HD IPS display, Wacom digitizer with pen, works equally as well as a tablet or laptop, very good keyboard.
Cons: Uses outgoing 3rd gen Intel Core Ivy Bridge rather than Haswell CPUs, very expensive (though prices seem to be dropping). No SD card slot. Fan skirt tends to catch on laptop bags when inserted.
