I have an X61 running almost perfectly on 10.6.2. Everything works the way I hoped it would, except perhaps random crashes of skype every hour or so. The more annoying thing is that battery life is very short, I get at best 45 minutes to 1 hour of use out of a fully charged, 2200 mAh (smaller version) battery. In WIndows the same battery should give about 3 hours. Anyone experience something similar?
