Thank you so much for your answers guys, wow, I really enjoyed you comments while reading
For me the white color was obvious cuz I always wanted a white Apple product but I couldn't get one, but this time "it was the time" and they also match my Beats by Dr.Dre Studio headphones (also in white).
I'm so exited to hold the Retina display in my hands, I believe it'll make the difference a lot from the previous iPad 2.
About the connectivity, I didn't need the 4G/3G version cuz' I think to tether my internet connection from my phone and I have wi-fi almost everywhere (home, work, cafe/pub)
About the size, 16 GB is just not enough, 64 is just to much, and I think 32 fits perfectly for me

...also I think that since I use a Canon DSLR I'll add my photos in my iPad so HERE COMES RETINA AGAIN
I'm glad that everyone had a positive feedback about my choice, you made my day, thanks
