I am thrilled to see a LaTeX app come on the iPad. This just change completely the possibilities to use of this device. I purchased it to be able to still work on documents on the go. It often needs to download stuffs when compiling, so it sometimes fails to compile, but even then it is very useful to be able to edit the documents on the road, in a plane or in a train.
The app is still not perfect. It would greatly benefit from a true search replace. The pdf viewer is often slow / or bugs. Also, it would be extremely useful to be able to send documents by email.
The day when I can completely write a research paper or a course on my iPad is still far (I would not like to try any of these without a good version control system anyway), but this app allows me to use some time that would otherwise not be so productive, so I would like to send a bit cheers to the developpers and encourage them to keep up the effort...
