You're biased by what you experience first.
Seeing my cousins original gameboy from circa 1989 with that puke green screen turned me off from handhelds.
Black and white would have been better.
Even though my NES/SNES/N64/DC were displayed on a 19 inch CRT, I felt that the handheld screen was too small to enjoy.
Ive had a smartphone for exactly 10 years now, but I have played games like angry Birds on it only a handful of times.
Someone with a iphone showed me a SF4 port one time but it felt weird doing qcf/hcf on a flat surface instead of a dpad and your thumbs would obscure the display.
Anyway, I'm sure Million is saying 10 Hail Marys for my soul right now lol.
