I personally wouldn't call them overpriced as much as when Steve Jobs was there. But with the new airs becoming quite a good value, 256GB SSD MBA for 1k, compare that to a Vaio Pro at the same spec you say be looking at around £100-£200 more, not exactly sure. As for the rest of the Apple line up, quite overpriced...
As for phones, yeah, ripoff, on Android you can get so much more like a bigger screen etc for the same price.
Tablets, this is arguable topic many would say including myself, even though you can get an Android tablet for much cheaper, you don't get many tablet optimised apps,
TV, who cares? doesn't everyone have Sky/Virgin or just use a games console with Netflix? Personally think Apple TV is just a way of paying for Apple tax on their library.
Customer service is really where Apple shines, from their premium you get a round the corner Apple store that sorts everything out for you in a jiffy! and a very good customer support team on the phone.
Phone/tablet: Android, because value/I don't have a tablet, don't see the point imo.
Computer: Windows, wasn't really interested until the new MBA hit the market, but interest now!
TV: Console and Sky, really couldn't give two ****s
Disagree with me if you want, but this is my opinion and you are entitled to your own so don't give me hate
