Apart from the issue of graphics being hard to position, your other criticisms of LaTeX are more to do with its UI or lack thereof.
If you want to use LaTeX to produce your documents but want an easier way to use it then you should really check out LyX. It's a GUI front-end to LaTeX and address several of your issues: it makes LaTeX easier to learn (in fact, you don't have to even know LaTeX to create a simple, mathless document), it's more intuitive, and it saves you typing. It also adds spell-checking, better graphics handling, navigation, and more.
Because LyX is merely a front-end to LaTeX you still get beautifully presented documents. LyX documents are also plain text so version control works well. In fact, LyX has support for subversion built-in.
If you haven't already guessed, I heartily recommend LyX. I wrote my entire PhD thesis using it and found it very worthwhile.
