I need to purchase a tablet with stylus for my classes. In the past, I use a Windows with Microsoft Journal, but I absolutely hate Windows. iPad Pro is a promising alternative, but it doesn't look like it can deliver my needs at this point. My workflow: 1. Prepare barebone lecture notes with Powerpoint 2. "Print" the Powerpoint file to Journal format (.jnt), (kind of like printing a file to .pdf) 3. Connect tablet to vga projector, open file in Journal, and write while lecturing (mostly short phrases, and solving lots of mathematical problems). So my need of the pen functions is very basic (different color pen, an eraser, and some highlighter). 4. Journal can save all my writing in .jnt, and the file can be shared with and viewed/edited by any Windows computers. This is important as I still want access to these files years in the future, even when I no longer have the tablet. 5. If needed, I could also convert the .jnt file to .pdf for posting (e.g., to Mac users that couldn't open .jnt) By the way, the 'best' app I could think of is Onenote. But the file structure is very poor, in handling hundreds of pages of powerpoint slides, into multiple files. For example, I can't have one file per lecture. The 'cloud only' file storage is also another huge limitation. Right now, due to the lack of a suitable app(s), I don't see how the iPad Pro could achieve all of the above. Please comment if you think I missed anything about the iPad Pro. I would love to be proved wrong, and buy a iPad Pro instead of a Surface Pro 4.
