I have paid for just about every app out there and used all of the active (an non active) pens made for the iPad. If your serous about note taking let me save you some trouble. Great YMMV, Make sure you can return what you try! (Best Buy is a good source for pens) Lastly, someone more than likely reply to this with a 'My (insert app here') works perfectly with 'insert pen here' or claim the cheap nub stylus is all you need. Anyone want to take a stab at a price point for the 'Gold' iPen? IMHO I feel that Apple will release a tablet later this year we all know about already called the 'Pro' series that will more than likely have an Apple pen (iPen?) as I'm sure they have seen the Wacom's and other $59-$100++ pens come to market and all perform badly - There is some money being left on the table at Apple they will adapt soon! The good news is the 'Pro' tablet will be large 12'-12.9' very thin and light with the large screen giving you a nice working surface to write on - The bad news is it will be very expensive even before you buy what is sure NOT to be an integrated pen like Samsung's Note series as it will be its own profit center. I believe it is extra for a Surface, I don't know. If this is something you're committed to trying for say work meetings etc you need to look to either a Surface device or a Samsung Note series tablet designed for (and supplied with) the proper pen. Why is this? The iPad is not designed for digital pen interaction it wants to see your fat fingers! The Wacom 'active' pens try to circumvent problems like palm rejection, adding pressure sensitivity through Bluetooth connected programs. Others have you write along the bottom in a box (the one that does this has not been updated since 2011) I think it is called Pendulate or something like that. one app will have you writing than trying to 'lasso' what you wrote and tap, tap tap to conversion. Palm rejection is hit and miss and the interfaces are usually clunky. They will work as expected (or desired) about half of the time.
