Funnily enough, I upgraded to an LED TV from a CRT just last week. My old TV was 14 years old, still a good picture and the sound was better than the new one (would need a soundbar to match it). I only did it because I was getting fed up with watching streaming stuff on the PC, and was finding that subtitles, scores etc are now displayed so small that they were hard to read (broadcasters expect you to have a bigger TV now, obviously).
I could have upgraded much sooner. I buy toys when I want them. There's nothing for me to save for, really. Interest rates are so low you're almost losing money by saving. I have a house, and the jump to upgrade that by moving would be too great (and bring too little benefit). So I agree, in the main - might as well have what I want when I want it.
And in context of this article, I'm an android user. Just prefer the interface. I prefer having live widgets on the home screen, and there are some useful apps that don't exist in the iOS world due to the sandboxing of applications. I like the auto backup of SMS to email, for example, and don't think an equivalent is possible in iOS (may be wrong, but couldn't find anything).
