I believe hard was mostly right. The only objection I have is the gamecube/wii being so low on the chart. I only own the cube (out of the two), but there are a ton of good games for that system.
My version:
PC> XBOX> PS3> MAC> GameCube/Wii> PSP> DS> Nintendo 64> SNES> Atari
BTW, I love my PS3 and DS greatly.
Gotta love DS 
Mario Cart DS is an awesome game xD The only problem I have with PSP is the lack of games 
You get the occasional good one, but most are… crap.
Yeah, I gotta agree. The thing is, I use my modded psp for all sorts of other uses, so it really is better than normal. UMDs, ISOs, Music, pics, vids, and I emulate the SNES and gameboy on it. Cant really go wrong playing classic titles on it. It kind of beats the old systems cause it lets me control the system much more. Quick save and load is a life saver. Just went through many of the castlevania games, and metroid…
You cant really compare hand-helds with others…
I will also only compare what I have played on.
For me it’s:
CONSOLES/COMPUTERS
PC(Including Windows laptops)>PS3>Wii/GameCube>XBOX>MAC(Including Apple laptops)>PS2>PS1
HAND-HELDS
DS(all varieties)>PSP(these 2 at the top are really close)>GBA>Gameboy Colour
also in terms of design and looking nice (i havent used it but)
EVERYTHING> WiiU
WiiU>everything in the world
loljk.
I don’t really care about order other than that the PC is always first.
my xbox>my laptop
