There is nothing like the convenience of having everything in one instrument. On the other hand, any keyboard with built in sounds can be enhanced with a 4-pound laptop running Jammer Live. Well, two midi cables may be required.

Jammer Live does not require a server class computer. (Gigasampler almost requires this, but Jammer Live can be used to play the sounds in the keyboard instead.)

I bet there are gigging musicians that would not mind having an 88-key Yamaha S80 with a 4-pound laptop (and two midi cables)running Jammer Live. In fact, one could visit a friend or location with a keyboard available and just bring the laptop; how is that for portability?
