iTunes a 76MB app, that takes almost 100MB just to launch it? For a "Jukebox" app? It's bloatware to people who actually know a bit or two about computers and software. But hey to each their own.
who gives a crap about the 'figures', it opens in a few seconds, works flawlessly and features pretty much everything you need for the target audience. any product or software has a target audience and a brief to please, iTunes seems to know who it's aimed at and does the job as well or better as its target audience would hope it too. maybe your advanced computer knowledge should be directed at cleaning up your mac. If it's having trouble running iTunes, it must be pretty crappy for getting any work done.
