Along with the IMM737, iLuv also launched IMM517 which has an adjustable tablet holder. Instead of using a wired keyboard like IMM737, it features a Bluetooth keyboard for wire free experience.
You also get the amazing jAura sound technology for superb sound output. The whole setup does have a slight iMac computer feel it. That said, I would still go for the Imm737 as I am not too fond of changing batteries every weekend.
