I bought my first Apple, a Apple II, or some such thing in college (1982). I learned to use a mouse on my IIc.
That said, it's been a while. Haven't owned a computer in quite some time, though I usually find myself on Windows when I have one at my disposal (e.g., employer's computer, net cafe).
I don't like Starbucks because, as I like to say, I want my grandkids to have a choice what coffee they drink. By extrapolation, you can guess how I feel about Microsoft/Windows.
I preferred Beta too.
