I recently switched to mac. I love it.
I have a macbook.
Previously, I always built my own PC systems. My last one is still running fine electronically- it's about 6years old. I got to the point where I needed a laptop.
My reason for switching from pc was irritation with Windows, and the increasing incompatibilities of certain hardware components running under a PC setup.
So now I have a macbook, and almost everything is great.
I had to get office:mac for .doc documents and xl files. I have a hotmail address.
My only problems with the mac have been related to MSoffice software, which is forever having updates for security issues (de ja vu...), and which has crashed approximately 50% of the times it's been used.
I'm not sure a drop test onto concrete is a realistic test of reliability and return to operation. Yes, a pc will be fixable quickly in this situation. Once you have worked out if this grafix card is compatible with that bus, or this SP on windows. If the new chipset is going to have USB crashing issues. All stuff you have to keep current on.
Day to day reliability is significantly better with the mac.
