However, it should be noted that none of the free trials is running on startup or running in the background--which is what REALLY irks me about new Windows PC's.
I never had a problem with trial software on PCs. Not an argument for them, however, as I always had the restore disk in there as soon as they got out of the box, and they would get a fresh OS install. If the worst thing on my MBP is office suite trials that I can delete very easily, then that's fine by me.
