Console is the 360 and handheld is the DS. Both are superb third party magnets with a well implemented first party of offerings as an extra. I love the DS for it's plethora of niche titles, and the fact that it's hefting retro gaming on it's back. I like the 360 for some great console titles, great online and XBLA, which will be getting Castle Crashers soon and my world will be complete.
I own the Wii, 360, PSP and DS. I will be getting a PS3 sometime around MGS4 in June.
