I seldom upgrade my phone to the latest and greatest these days. Not willing to pay a premium price for it. I don't use social media - but what I do use is maps and travel information, and information seeking, as well as diaries and email - so useful for that and planning life etc.. My phone is my only camera as well, so the only thing I "get" about having a top rated phone, is one with a good camera. I like taking pictures, so that is an important feature for me.
However, I also, shock horror, use my phone as a communication device!! It's what I use it for 75% of the time (the rest is mainly pictures, and email/diary, maps and looking stuff up). I have a couple of games on it to play on the commute, but generally I read a book.
For buying stuff or doing anything online, I use a PC, be it flights/holidays, tools, food whatever, I use a PC. I can't see myself ever using my mobile to do that. A mobile phone is a useful companion, but not essential.
So I totally agree Lie - I don't see the point is spending a lot on a top model phone.
