Can we all just agree that to be good at any technology, it is pretty darn hard? But I've done enterprise Java/.NET, web development,and iPhone development. If we are talking about what is easier for a beginner to pick up (some HTML/CSS/JS with something like Rails or Django backend), I would definitely recommend web development over Java/.NET/Obj-C.
..I feel a little differently. The thing that just drove me crazy when I first tried to learn web development (with rails) is that every so often, I would need to make a detour, and go learn some other technology (css, javascript, prototype, html,http etc) . Granted, that experience may have helped my learning curve for objc; But when I was learning to program for the iphone, I was up and running before I even fully realized that cocoa was different from objective c. Of course, I cringe when I look at objc code I wrote early on, but guess what? The people who purchased those apps know nothing about the underlying code.
