Guys you totally need to get Jotter. It's five dollars but it's totally worth the price. It's like a modified version of S Memo, it uses the S-Pen SDK, leaving out the bloat (voice notes and such) and adding the most important feature: HUNDRED PERCENT PALM REJECTION
I really need to use caps because this is so important. You can rest your hand on the screen, just like that. You can even disable the back button, and switch buttons of you're left-handed. The app is very simple and very intuitive. It's so easy to use I prefer it over dedicated drawing apps, for example.
I think Jotter is the first killer app for the Note, hell it's what S Memo should have been from the start. Btw, with the latest Gingerbread rom lC1 Samsung has added palm rejection, but I'm not sure if it's as easy and intuitive as Jotter, and anyway I didn't want to wait for Movistar to update my rom so I just threw 3 euros at this app. Come on, a real pen is 2 euros and you have to buy a new one every couple of months. You're actually saving money.
Reviewers who said the S-Pen was a gimmick were just clueless. With Jotter and Soonr Scribble I find myself using the pen every day for things that are simply impossible for other phones. I can't completely replace paper sheets and pens.... Yet. We'll have to wait for a Note 10.1 or an even bigger one, but hell, this is the start of something huge.
