I'd probably have no problems with HTC per se - but I don't want my phone shut off, reposessed, or whatever you call it when you buy your own, or any other hassles due to a patent squabble. I like my Nexus. Things seem a little weird sometimes from a carrier based non-rooted phone, but I'd buy one from Google. I've had a few Samsungs and they aren't too bad. I'm still miffed that Motorola wanted to charge ($50) for their phone management suite when every other maker gave a CD with the phone. The BB Pearl had a CD with a management program, so does the Nokia 6085.
I could download OVI for the C6.
All I wanted to do was to install the ringtones I wanted, and not what Motorola or the carrier wanted me to have. BitPim started me off on the whole idea of rooting.
