I got a lot of stories and probably gonna be a wall of text if I includes the previous consoles......so I'm gonna write the latest ones only.
First, handhelds. I'm studying abroad, and here where I'm studying the home consoles are very expensive along with most electronic products like TV, smartphones, etc. and I'm not really rich though 
3DS: I was excited to play Super Mario 3D, REvelations and Kingdom Hearts 3D and its worth it. Also the upcoming games for 3DS is also quality-wise so that is a bonus to me 
PS Vita: my 2nd purchase a year after 3DS and my studies are far from over. And to my surprise I had more fun playing it than my 3DS with more games. Even I had the hard time catching up with its library
Now, for the home consoles;
PS4: actually its my brother's. He's a long time Sony fans from the Walkman's era. And his friends and our cousin got the PS4 as well so that might triggered him to immediately bought it lol. Oh and he's also a Killzone fans.
