I have had essential tremor since I was a kid. So did my 2 boys. Yes, you can get it when you are older.
The reason I hate Apple (it may be irrational) was when Apple started selling computers. I couldn't afford them. Apple stopped retailers from discounting. Steve Jobs had a good business model and when they had a good product, they would try to get people to buy stuff in the Apple universe (Itunes, etc.)
Luckily for me other PCs became cheaper. And so I own a bunch of PCs. Tablets are good for some things, and rotten for others.
Win8 is really best only for touchscreens and stinks for regular PCs. So if you have a regular PC and want to dump the UI, download something free (google Classic Shell) or some other products for a few bucks. You can go back and forth between the Win8 UI and the Win7UI.
The reason I posted is that I am still interested in an Android tablet. If somebody gave me an Ipad, would I take it? Yep. Would I pay for it? Not now. I like to see competition and so I like Android.
BTW I am 63. Yikes! A zombie. If you were offended by my Ipaper joke, you are older than my university students.
