I'm not bashing Mac here (bought my first MBP a few weeks ago) but I find it very hard to get decent AVCHD editing and exporting on the Mac. I tried both iMovie, Final Cut Express and Adobe Premiere (trial) but my MBP just doesn't cut it. It's either way too slow and viewing AVCHD movies is just a plain horror. Today, I tried Windows7 with Vegas (trial) and this is night and day difference. Windows7 plays AVCHD fluid without any additional codecs (!) and Vegas makes editing them a breeze without having to convert them to a (less good) format like FCE does. I really hope there will be decent AVCHD solutions for my Mac one day, but for now, my video editing will be in Windows7 only. Too bad.
