Dear Members:

Maybe a silly question from a newbie, but here we go:

I've bought a new D90 (+ the 18-105 mm kit) 1 year ago and since then I'm very happy with all photos and progression with my technical habilities. It's been a whole new world for someone with almost now photography experience. Some D90 books (including Young's Mastering the Nikon D90), the Nikonians forum, sharing experience with my friends and that is it. Almost forgotten those days of my old Canon A1 and Canon PowerShot S3 IS.

Now I've the possibility to buy the new D800, but I'm a little bit concerned about my real needs. My chief considerations are:
a) the D800 price;
b) the potential gain in photo quality versus my technical level and experience;
c) my personal feeling of a kind of "programmed obsolescence" that is so evident nowadays, not only in the photography domain, but also in the information technology (iphones, smartphones, ipads, tablets, etc, etc, etc.), with all the consequences for the environment.

All comments, opinions and advices will be extremely welcomed.

My best regards to all,
