Same, sometimes pen and paper is just better for my needs. I keep flirting with digital pens. The idea is awesome, you write with a pen on paper and it's automatically digitized and backed up. (There's special markings on the paper to help the digitizer). In practice there's been some glitches, but in the worst case it's still paper and ink.
I tried a Livescribe Echo pen for awhile. It always felt kinda bulky in the hand, and there were some glitches. It also had audio recording, and probably the best feature was you could point at your writing and it would fast-fwd/rewind the audio to the moment in time that you wrote that word. Great for filling in gaps when taking notes. Livescribe tried to integrate with Evernote at some point. Seemed like a great idea, but either Evernote or Livescribe failed terribly on that integration. Lost functionality from the stand alone Livescribe app, and never gained the functionality of Evernote. Ultimately my pen fell prey to a failed OLED problem that many of those pens had.
Recently trying again with a Neo Smartpen. The first one had a firmware bug and after a few days it couldn't re-charge anymore. Customer service replaced it, and replacement seems fine. This pen feels much more like a regular pen. Power on/off is triggered by removing/replacing the pen cap, so I barely even notice it's not a normal pen. Digitizing quality has been solid. Not as many features as the Livescribe had, but the transcribing quality (OCR) is much better. (Of course, I'm comparing a brand-new Neo to a previous-gen Livescribe. Could be cool to check out the new version of Livescribe, too)
