VERY good point and honestly one that I hadn't thought of. I'm not aware of any publicised cases of Jobs calling out an Android phone but I would believe it, he was an asshole. IIRC he was so anti-android b/c he saw Android as a blatant rip-off of iOS (not weighing in here on either side).
As far as cost of macs I think it's still worth it even if you want to run Ubuntu as your OS b/c they hold their value better than any other laptop I've seen on the market. They also resell FAST which is very nice.
I buy my computers to use them, not to resell them. At this point my Macbook Pro is worth maybe $300, and I'd be more likely to gift it to a relative than sell it in the first place.
I also found it to be a huge pain to install Linux on it, which is why all my Linux computers are Thinkpads (with the exception of the old HP workstation I'm typing this from).
