No I do not use them, but I still have a retired 4S sitting in a cubbyhole in my desk.
Besides I’m invested in Apple through indirect subsidies because of their Tax Dodging. I consider it a receivable. It’s almost like my tax investment in GM.
No, you aren't. Apple has been one of the three largest US Corporate Income Tax payers in the United States, and in 2012 was the largest, paying $1 of every $40 of US business Income Tax collected in the US. Apple's effective Tax Rate last year was 27.6%. Compare that to Alphabet/Google's effective tax rate of only ~18%.
