Go also lets you use a Dual Shock Controller.

Summarizing doesn't quite do it justice but they notably highlight PSP-2000/3000/Go over Vita and PSP3 for 480i output to a television that works perfectly with PS1's 240p.

No one mentioning the My Life in Gaming 206 video that compares playing PS1 games across every option: Well, you need custom firmware in general to play your ISOs or eBoots that you didn't buy off PSN. Good topic for a conversation since PS1 is so widely supported across Sony consoles. Now, If I were OP and had to choose between a used PSP and fiddling with emulation of questionable quality on a hacked Vita, I'd choose the used PSP every time. I have a $50 Android device that I pretty much only use for messaging. And smartphones are generally low-powered enough that you can keep them on all the time, which is handy for messaging.

I live in an area with rather inefficient public transportation (though I try to take the bus when I can), but if I were in urban Europe or Asia I know I'd sell my car in a heartbeat. Desktops are indeed far cheaper, but there are times when I need to take my work with me, so I also have a laptop. I don't own a watch since my basic phone already tells time. Why use a smartphone when your computer is more powerful? Why wear a watch when you can just look at the clock on the wall? Why buy a laptop when desktops are cheaper? Why buy a car when you can take the bus?
