Samsung Galaxy S2 owners thoughts?

[MaxTheLimit]

I just grabbed a Galaxy S2 and I'm going through the process of getting it working on Rogers.
I was wondering if anyone else here has done this, and what sort of tips, pointers, opinions or thoughts on the device?
Any potential pitfalls I should keep an eye out for?
This is my first big investment smartphone. I started with an Acer Liquid E ( just to test the smartphone waters ) about a year and a half ago, and I have really gotten close to the phone. So I figured I'd invest in a good one now.
