I also read something about a pen that had a side 'action' button on it, that when you pressed it (or held it) it would perform an alternate task (instead of making a line it might erase, bring up a menu, hold to drag, etc.) Does anyone know how that works? BT I would assume but it would be great to be able to do that on our tablets
Also, is the digitizer sensitivity matched in any way to resolution? Since we have a higher resolution than most tablets would the sensitivity be better and more fine grain.
Yes, the digitizer is supposed to be very good on the Infinity. Take a look at this comparison between the Prime, TF300, and Infinity: (apparently I can't post links yet, so just Google "android police transformer buyers guide" and look under the "Benchmarks" section for the comparison)
As far as the stylus you're describing, it sounds like the Adonit Jot Touch. Read the last few posts on the previous page of this thread (starting with post #27), as they discuss it a bit and provide a link to its product page.
How is writing with resting your palm on the tablet?
Is it recognized?
Or is writing not working then?
This is handled on a per application basis. The application I've been using, LectureNotes, has several different settings for this depending on if your stylus and/or device is capable of tracking the position of the stylus. For the Infinity, however, I've been using heuristic palm detection, which kind of works. I'm still trying to tweak it to see if I can get it any better, but at the moment it seems to work at an acceptable level.
