Summary: I love the added battery life afforded by the "clam shell" extra battery - I get easily a full day of unfettered use. I am frustrated with the stylus. I replaced my old Lenovo X201 when the hinge began to fail. I had trouble free use of the stylus (a Wacom product) with my X201. With the X230, I have had continued problems with calibration (poor at best despite numerous re-calibrations and updating driver).
Summary: I like the computer. It is light weight. I can work on the computer unplugged for most of the day. I particularly like the digitizer that I can mark on my power point slide. I do have problems with the USB connections on this computer. They were from time to time disconnected for no apparent reason. I had to unplugged the USB drive then re-connected it.
Summary: I've used a number of x-series Lenovo laptops, including the awful x240 (see separate review). The X230 however has never let me down over 2 years of mostly daily use. It has a good keyboard is plenty fast enough (Windows 7) for normal office use and has all its keys in the right places (unlike x240). Recommended.
Summary: The Lenovo X230 Tablet is an amazing product. It is lightweight, solid as a rock and well designed. The multi-touch experience is better on Windows 8.1 (W8.1) Professional. I do not recommend using it with Windows 7 Professional (W7) since W7 is not designed for touchscreen features. The Lenovo X230 Tablet is the perfect companion for scholars, students or consultants. You can read books or articles on the screen.
Summary: I bought this as a replacement for the X220. I don't know why some people bitch about it, it is still the best laptop around. Fast, light, AWESOME battery life. The old X220 seemed a bit sturdier but the X230 has improved CPU and performs really well.
Summary: Anybody who is having issues with the trackpad try turning off tapping and gestures. It makes a world of difference. Trackpad is virtually unusable with these features turn on with them off it is one of the best I've used.
