I've had Advance Wars DS and Final Fantasy V Advance in my DSlite for most of the past three months. I'm just about to finish the hard campaign on AW and working on Omega Mk.II and Neo_Shinryu in FF. However the biggest timesink for me has been FF3 and since I'll be starting FFVI Advance soon, I'm expecting to to pass the 500 hour mark, though that is over a span of 13 years.
