Lately I find myself enjoying handhelds more than console or PC, with handheld systems you're not stuck playing games in one place, you can enjoy handheld gaming in any room in the house or even take it outside. Sure handheld systems might not be as powerful as say a PS4 or gaming PC but the 3DS and Vita are still way more advanced than anything I grew up with.
Also systems like the Game Boy, Game Gear, and of course the Lynx are highly collectable and very affordable to collect for, collecting handheld cartridges almost feels like collecting trading cards, and their doesn't seem to be as much attention on handheld collecting versus retro console collecting so I generally find better deals on games.
