Was going to keep up with Apple for a while - but I've decided this Macbook will be the first and last new product I buy.
The new Mac OS coming this year sets to break an interface that never needed fixing to "align" it with what is fast becoming "DumbOS." I won't be upgrading - even if for free!
The Mac OS interface - its nice, but coming from modern Windows systems I miss some of the "snap" features. I also dislike how programs don't stat fully maximised (MS products, particularly), and you have to do that yourself.
I DO like the tabbed Finder interface. That and colour-coding files/folders is a very nice touch.
If it wasn't this machine, it would have been a Dell or Acer notebook. We know some hardcore "brainy" Apple hardcores that wouldn't have anything else. You can't put PC in their mouth without them spitting it out.
But I reckon that most of the people who switch to Linux become VERY brand loyal. Another person I know prefers running Linux/BSD on his Macbook
Other brand loyalty - None in this family, really. Many years ago it was Ford Falcons, and another relative still gets a new Holden (GM) Commodore every couple of years, but thats about it.
We've a mixture of appliances (F&P/Westinghouse/Panasonic/HP/Apple/JVC/Onkyo/Denon etc).
