My dad came to America in the early 80's and the first personal computer he saw was an Apple. And my first computer was an Apple. They are expensive, sure, but not like they were back 20 years ago.
My parents raised me with a philosophy of always buying what you *really* want. And really, people who want a tablet, but *really* would prefer the iPad, just need to get the picture that they should *really* be saving the additional money for it and NOT wasting it on a Kindle Fire or Nexus 7. It felt *really* rewarding finally getting my second (I had a 2006 model originally) MacBook Pro after a whole year of saving.
I don't judge people for their phone either, but I do judge people who buy a new Kindle/KF every year and say they wish they could afford the iPad while buying book after book. The same thing with people who buy a phone, but then wish it had been the iPhone. It's the whole, "I didn't really wanted it to begin with, but bought it anyway" thinking I hate.
I also judge people who play games on their phone, but that's me coming from the early days of the iPhone 2G when it was just apps, music, and the internet. I had a Pocket PC with Windows Mobile. So it's always been about using a smartphone/tablet as a smartphone/PDA and not some entertainment center.
I saw some 55+ year-old old guy playing Candy Crush Saga the other day. He was talking to some older lady about it too, trying to get her to download it. It was actually pretty sad. Two old people discussing the Google Play Store is pretty sad. (and okay, they were related to me.

)
I play games too of course, mostly Humble Bundles, but otherwise I'm more into using my phone for tasks, the weather, e-mail, and quick Wikipedia searches and IMDB.
But yeah, I agree with a lot of people here. If you judge without knowing someone, you're only fooling yourself. But there are times where you can't help it because it's just bizarre at how some think.
