Personally I download only MP3s and bring them in to iTunes from my PC in order to maintain my ability to easily cut ties with the iTunes eco-system (not as convenient – but better) Regarding Apps – I just try to never purchase them. Although irritating it is relatively easy to keep dependencies on any one company light and integrate data where it matters – mail/calendars etc..

For me a bigger bug-bear is is being shoe horned in to specific options; for example Apple’s maps update – where I can no longer use the far superior Google Maps App – as it is convenient for Apple’s business strategy – this has seriously pissed me off.
