I liked this piece switching by Bill Westerman on utilware about switching over to a Mac. What caught my eye were his points about the productivity of fewer choices:
You’ll be amazed at how few things there are to modify
I was the ultimate tweaker in Windows – registry entries, options menus, toolbar buttons – and was taken aback at how few things there are to tweak on the Mac. At first it seemed to be restrictive, but I’ve realized it has actually freed me to do things other than tweaking.
There isn’t as much stuff to buy for a Mac
If you go to the local Fry’s or Best Buy, you’ll find aisles and aisles of stuff for Windows, a few things (like USB Keys or mice) that work on both Windows and the Mac, and if you’re lucky, a crappy little shelf of Mac goodies. But you’ll also likely find that you don’t need to buy all that extra stuff, as a lot of it’s not necessary with the Mac.
You’ll get more things done
Once you get over the bouncy icons in the dock, and exploring all the built-in applications, you’ll probably end up spending a lot more time getting things done with your computer, and less time doing things to it.
Truth be told, we spend far too much time tweaking our computers and not enough time actually working. I’m not a massive Mac user, but this kind of post inspires me to spend more time on my rusting PowerBook.
