It's an interesting situation for me.
Last December when I was going to US for a job, I left all my consoles behind. I was even thinking of leaving my DS, but as a going away gift, a friend got me TWEWY, Advance Wars Days of Ruin, and Prof. Layton, just because these were games he always recommended, but I had left gaming fall a lot by the wayside in the time leading up to my leaving.
Obviously I had my iPhone. So with no consoles, I kind of dropped gaming nearly altogether. I did play through Layton, and kind of forced my self through Advance Wars over the course of 6 months, but the DS never rekindled my gaming desire (although I did stare longingly at all the new console games coming out). I thought the DSi may kick start it again, but until FLipnote, there wasn't much that was appealing.
To me the iPhone was the saviour. For someone becoming increasingly less interested in long titles, the pick up and play mechanic of the majority of iPhone games was fantastic. It's not so much the platform, but what the platform means to developers. Quick 99c games were kinda neat for me to toy around with, even if I didn't seriously play them.
