Laurent Bossavit talks about his experience switching to a MacBook.
I was surprised by his first issue - my MacBook Pro makes no noise at all much of the time. I practically have to press my ear against the case to hear it. It may be an airflow issue for him, mine has a lot of clearance. To be sure, when it is hot, the fan is fairly loud.
I have similar issues with the keyboard, but since I typically plug a mouse and keyboard into my laptop, it hasn’t been an issue.
I do love the fact that there’s BSD Unix (the one true Unix, IMO) underneath the hood. It made me all giddy inside to be able to open a terminal and look at the /etc files and the /var/db config, etc.
I have Parallels running for my email (Outlook). It works quite well. The new version of Parallels looks like it will be even better.
And as for me, change has been great. I enjoy the challenge of learning the tricks and secrets of a new OS, and I’ve found some blogs that help with mac-specific tips and tricks - SilverMac is my favorite thus far.
And as far as reliability/stability, it’s been rock solid. Much more so than my woeful experience with Bootcamp, Windows XP and Medieval II : Total War (which is a disaster of instability, lockups and reboots. A pity, too, because Rome : Total War is my favorite game of all time.)
