Seriously, F# is awesome. These course notes and code examples explain why in far more detail than I ever could. http://www.itu.dk/courses/BPRD/E2010/.

Same use case. Love my Ipad. In a wlan network Readdledoc functions as a wireless file server that you can mount as a regular drive on any os, which is exactly what a caveman like myself who uses plain old file system operations for my document management needs. The downside is the IPad's somewhat clumsy overall file management imposed by the ios.

I've been working in the sofwtare industry since 2007 in a small team (individual projects ranging from 1 to 10 persons). We've always used scrum. Mind you, not by the book but heavily modified to fit our style. Seems to work if all participants are even a bit motivated and not totally clueless about the tasks at hand.

From the pragmatic point of view, there are two issues at play here. One - how to build decent programs that are maintainable and - two - understanding how such a program actually works. If your skills lack in the former, your code is probably near-to-useless in the long term for anyone. If you lack in the second - THE HARDER PART (pardon my caps) - then you are just partaking in a cargo cult that just happens to work because someone left you the tools that luckily get you the job done. I also think the second skillset requires a lot more effort to acquire than the first.
