But the thing is you don't need those extra things that require root or installation of another ROM. The phone will work fine without the OS upgrade.
Also, the only people who "need" those extra things are going to be the ones who know how to do them, or have the incentive/will to learn how to do such things.
"Work fine". Yeah. Until you get rooted because of unpatched security flaws.
One word - ZUNE. Unlike iTunes it was easy to setup, let me import anything I want, and I love the subscription service. I had Zune on my PC before I had any kind of mobile Zune player. Unlike iTunes, I get my music through Zune in MP3 format, and I'm free to use it how I want.
Uh, you do realise that the AAC format used by Apple is an open standard, totally free of DRM? Newer, and technically superior? Yes, you're free to use it however you want.
