Correction, it can be overclocked to 333mhz 150mhz bus , and if your insane enough to do it there are other ways to overclock up to 500mhz , but yet very unstable. The h1915 actual has SDIO sponge

... so it is basicly the same thing as the razor in expandibility other then the fact that the razor has jackets. If your not using jackets then the hp1915 is the same in an expandibility. The hp1915 is better at gaming , and I get up to about 320kb on video with out frame skiping at 200mhz on divx. Its got a better screen, better button layout, smaller, and it does a good job on emulators but the razor is faster in other area's. I would say go for it if you want to. Your not losing much. Over all the h1915 is prob better then the razor and because of the price drop and all the razor is actual worth less the then h1915.
