I've been reading this forum for months, some great items on the X2! As an aside, an HP Tech was remotely logged into my computer last night for 2hrs and fixed all the little problems I was having. I was honestly blown away by this guy's perseverance to tackle each one, esp my BIOS issue. If you are having issues, give their service desk a try. I've been researching Active Pens --- looking at comments here, compatibility chart made by a member and even looking through Amazon Reviews. I've narrowed it down to the Lenovo Active Pen GX80 and the new HP Active Pen T4Z24UT#ABA. Even though neither are officially listed as compatible with the Spectre x2, a number of people have reported they both work really well. Is this a good final list or should I consider others? With that in mind, has anyone here had the chance to test drive both of these pens? Comments on full functionality? Price is pretty reasonable, $30 for Lenovo, $40 for HP. My primary use of this pen will be for taking lots and lots of notes, handwritten overlays on PDF's, etc. For me, I need it to feel and act to as close to a pen as possible.
