I got mine in February 07, and then proceeded to play it non stop for until December, when I got a DS and continued to play Wii non-stop and then another year went by and I got a PS3 but then only used that for Blu-Ray and continued to play Wii non-stop, and now another year has gone by and I'm playing it non-stop. I may consider getting an X360 just for XBL so I can continue to play my Wii non-stop. Then i'll post a thread about how everyone has lost interest in the DS/X360/PS3. I wouldn't buy a PSP as (insert trolling reason here) but if I did I would still play the Wii non-stop.
(honest answer - this morning about 5 hours ago New Super Mario Bros Wii, prior to that, some Brain Training, Wii Fit, Mario Kart Wii and Punch-Out over the last few weeks.)
