Since i bought my phone pre-rooted from Craigslist, i've got a pure vanilla Android experience since day one. Some of my co-workers have various androids and i wish i could get some of the nifty "sense" and "motoblur" deals that they have... it's a two way street. Those with it want it gone, and those without want it.....
One of the reasons I love the Milestone, it's about as vanilla as possible. No Telus markings anywhere on the phone, no Telus software, no Telus boot animation..nothing. Wouldn't even know which provider I was with unless you checked the lockscreen.
