And......when Apple upgrades its operating system it has always been an incremental improvement. Never a huge change at the upgrade, but improvement. Never retrograde.
I bought my first PC from IBM, I think the year was 1982, maybe 1983. It was about $3200 then, maybe the equivalent of $5,000 today? It occupied a lot of desk space. Memory was 640K on the old, large, floppy discs. Printer was dot matrix and LOUD. And, of course, the operating system was Microsoft DOS. When Lotus 1-2-3 came out, I was in high cotton.
Apple products do not seem expensive to me, given how well they work and my mixed experience with Microsoft software. At age 66 I want a computer that starts, runs, and does the job without my having to fool with it.
I did not go Apple until Excel became available as a seamless install on the Mac.
From what I read in the Financial news, Apple still has a small installed base, relative to Microsfoft, but what growth there is in the personal computer category is all in the Apple operating system. Microsoft retains a lock on the corporate market but home users are surging to Macs.
For a short period, when Apple's stock hit $700 per share, it was the most valuable public company in the USA.
