Like the DreamTrooper, one of the first handheld Dreamcast systems. Speaking of which, as soon as I get the funds required for the needed PSU and battery pack, I'll be making one of my Dreamcasts into a portable
A mix of both, but as I'm a very busy person irl, I tend to lean more towards handheld gaming, as it's portable and I can entertain myself during long drives (since I'm never the one driving xD) and anything else that might be boring otherwise.
Wait..isn't console gaming just a tad same as handheld? o.o But I enjoy both, sadly I would be playing more handheld if I found my charging cord to my DS Lite. But until I find it, Skyrim for the 360 should keep me busy in the mean time. ; o;
