Tex writer is the best!!!
First of all, i am sorry if i am late to this thread. Coudl not help myself when i saw the topic.
I am a math & physics teacher. I got ipad4 so that i cud be off desktop to type all sorts of math question papers with greek symbols. I bought tex writer and i shud say that it it awesome !!! I type all my question papers in tex writer. I can clmpile them offline on ipad itself !! When i am satisfied with the format, i upload the pdf to dropbox. I use my desktop only to print it out as i dont have a wifi printer.
Thanks to tex writer!! I dont need MS OFFICE anymore !!!
