I have an x220 with both touchscreen and pen running Arch/xmonad. I almost never use the touch capabilities, though I use the pen a fair amount for screen annotation and photoshop. I like pens but if you are a serious developer on a laptop you are in text/keyboard mode most of the time and just don't need a touch screen, imo. Also, love the keyboard. I use the extra slice battery for it and get about 10-11 hours per charge on that slice plus the standard battery (real world, though I think they make a claim for more). I have a great lenovo charger that includes usb ports, but sadly I think they discontinued it. I use it constantly for charging my mobile devices even when not charging the laptop.
