The Black Friday and holiday week sales on iPad related products are already starting up. Here’s one great deal on an iPad productivity app for OneNote users. Outline+ – a OneNote notebooks app for the iPad with Dropbox sync – is on sale at more than 90% off. It’s down from its standard price of $14.99 to just 99 cents as a Black Friday sale.

Several years back when I was still a heavy Windows user, OneNote was one of my favorite applications. I installed Outline+ a couple months ago and gave it a quick try. I think it’s an impressive app, though I haven’t delved into it very deeply as I don’t’ use OneNote on the desktop anymore.

The app has very near 5 star ratings in the App Store and boasts a strong feature set. Here’s a little more detail on it via its App Store page:
