That said, the Surface Pro 2 looks really appealing.
I'm looking for a replacement for my iPad 2, but I can't settle on anything because all the non-iPad tablets have a widescreen, which I believe is poor choice when it comes to reading PDF textbooks.
Right now I read my PDF textbooks in landscape mode, and I use GoodReader to crop the margins, and everything looks fabulous. I'm worried that if I move to a widescreen tablet, I will end up with less vertical space and wasted horizontal space ("black bars" due to incompatible aspect ratios of the page and the screen).
How's your experience when it comes to reading these kind of textbooks? Any chance you could provide screenshots of how these textbooks look like when you read them in landscape mode?
Sorry if you already know that, from the way your comment is phrased it looks like you don't so I thought I'd throw it out.
Back in uni I was able to take math notes quite well by typing in Word. The math notation there is similar enough to LaTeX (including most macros for symbols) but types much faster. But that's not handwriting, admittedly.
I'm seriously considering trying to build something with the API. I'm not sure what; I just want to play with the cool technology. Perhaps an app which gives you an algebra question, then uses math recognition to interpret your working. It could then see that you made a mistake on step three (for example).
Perhaps I've just late to the party, but I'm still astounded that this is possible.

For reading pdfs, the widescreen is annoying and claustrophobic, and I haven't found any Windows PDF reader that is comparable to Apple's Preview application. Occasionally I've "printed" pdfs to OneNote, to read and edit them there, but this doesn't work great. (You can't drag pdfs into OneNote because Windows and pdfs barely work together at all.)
I used to do math notes on my ipad goodnotes since it has a zoom window.
This little-known feature is as old as Windows XP Tablet Edition....
I've read many math papers and books this way.
Btw, do you have a good way to read two-column papers?
Personally, I have to draw/annotate circuit diagrams and the Surface Pro is so far superior to paper it's not even funny. I couldn't imagine switching back - taking notes with a full laptop/keyboard just seems archaic to me.
From my times playing with tablets, Linux trails Windows 5-10 years.
