Raspberry Pi XBMC - Advice

I'm thinking of putting together a Raspberry Pi for XBMC to use with my HDTV. I'm not in the US so Chromecast, Roku, etc and other set top boxes aren't an option for me. The Raspberry Pi seems relatively inexpensive so I thought I might try it.

Has anyone got experience with XBMC on the Pi? Does it run smoothly?

Also I've got a Sandisk Ultra 64GB microSDXC UHS-I that I'm not using anymore. I see people selling parts for microSD use, but can I just put it into an SD card adaptor and use it like that? I'm not really keen on soldering bits, mainly because I haven't got a soldering iron.
