It was very nice, looked like an alloy case. One thing I would absolutely not want is the GPS feature.
Yeah, I have become a big Mac fan after getting my '11 Macbook Pro, and I make a living with PCs. iMovie '11 is easy, its just the assembly of all the different clips from a day out thats the work. Trimming one up is no big deal.
I don't encode from iMovie and the Apple H.264 Codec. Handbrake or MPEG Streamclip with X264 is better, faster, and more flexible. Sometimes I encode the final to DNxHD on the Mac, which is low compression cross platform codec, then take it to work and run it through the PC version of Handbrake to H.264 on my quad core Xenon box. That thing bangs it up in no time without the fans even speeding up. My MBP i7 is fast but throws a lot of hot air.
