I'm on a 9 month old Macbook and running just fine. It's a real computer. I worked for the other company located in Redmond for 11 years and was a Windows person for a long time. Both platforms will work just fine, both have software that expires over time forcing upgrades. It, planned obsolescence, is an industry, not company, reality. I got pissed I had to buy a new computer this year when some browser and PDF functions started to fail on my laptop...until I realized the laptop was nearly 7 years old. Hence my new Macbook.
But I had the same issue with Windows on and off over 20 years and in fact just lost several extensive documents of my railroad research--transcriptions of newspaper articles and original source documents--that I'd created, because Office no longer supports the version of software they were created with in the 1990s. Thanks MSFT. But really, mea culpa, I (and all of us) need to stay on top of updating not only computers but also documents and spreadsheets to remain usable. Heck, even this forum got caught up in the realities of technology.
Fortunately I have hard copies of those documents that I'll be retyping into Word. Nasty but at least I have something.
