I have an XPS 12 (maxed out specs) in preorder limbo and noticed the Samsung ATIV 700T had a true pen compatible touchscreen. I need a moderately powerful laptop and I also want to shift from printing paper forms and giving them to clients to having them sign the form on the touchscreen with a capacitive stylus. I expect the software isn't there but I want to know when it is available, is a capacitive touch screen sensitive enough to take a legible signature. I looked at Grahl PDF Annotator 4 and it seems that would work for signing and claims to be Windows 8 compatible. The reduced specs of the Samsung (i5, 4gb ram, 128gb ssd vs double specs on the XPS) worry me, but at that reduced price it would only have to last 2/3 as long as the Dell to be the same value. Again, most of the time I expect to need a laptop as a laptop but I want the ability to convincingly get forms signed. Suggestions on another unit or experiences signing on capacitive screens? I'm not doing art, just taking a signature.
