Ohh now only i saw this topic. i got myself a 512mb MMC for my qd last week. Got lotsa Songs,movie and games inside my MMC already. The movie is superb, i got few episode of anime inside. A 30min anime after convert is around 22mb.
Best song player for qd i would say is oggplayer, free and sounds good. convert the songs into ogg format each song is less than 1mb big, mostly 800kb.
The worms world party demo is so fun, cant wait for its release.

yeah using transcend 512mb memory. By the way i din notice any lag. Maybe a bit lag when u put in the mmc card into ur phone. the phone also need to process what's on the mmc ma just like u plug in pen drive into ur pc also need to wait a while.

The lag i heard is when u got big mmc card the original ngage music player will take few minutes to load up the playlist, but they said u use 3rd party mp3 player then can solve the problem already.

I bought my transcend MMC 512mb for RM190 at lowyat. alot shop selling there can bargain.
