Usually the people who bleat on about how they love Macs miss the same old points:
1. Why is Safari completely pants, OK MS decided to invent some html extensions and javascript manages to accommodate the changes required but for some reason Safari failed to keep up? At last there is a (non Mac) solution for Mac users now.
2. Why did you have problems with your Wintel machines before you converted to Mac - was it becuase you were incapable of not fiddling, or becuase you loved the HUGE choice of free Wintel software that you had, so much that you could not resist downloading lots of junk and screwing up your registry? This is a user problem, not an MS problem.
3. MS is a controlling monopoly that restricts choice? oh right just like Apple: When I buy some music to download I have to get their permission to play it on another computer (and a max of 5 computers only) - what kind of company do you think Apple is...if they had the market share of MS they would now be behaving just like MS.
4. Macs are perceived as more reliable, but this is becuase they have less hardware choice so the system has a limited set of drivers with which it interacts, no other significant reason. Install an MS operating system on a PC with MS office, install a firewall and set the MS auto-update active, don't fiddle, and you will be fine. I am writing this on a PC I got and set up in 1998, I have only added more memory since then, and MS auto-update does everythig I need for the OS and office.
5. Sure you have a unix based OS under the hood, and sure this is fundamentally better than MS, but this is not root cause of your issues, it is how you manage your PC that causes your problems, you can screw up any unix based OS if you fiddle, just as you can a MS OS.
