Bluetooth speaker support?
As for browsing speed... that's a processor bottleneck. First of all it's a low-power-consumption processor to begin with, and then it's slowed down even more to further decrease power consumption. That's why the iPod touch has a 5 hour battery life instead of a 2 hour battery life. A faster processor with otherwise current iPod touch technology would cause the battery life to go down the crapper. They'd either need a dramatically improved processor, or a fatter battery. Rumor has it an
Atom might be coming to the next iPod touch, but I don't know what the comparisons are between the current processor, as far as speed and power usage go.
