Any interest in the new chips MSP430F22x4? (Where x=3,5,or 7)
They also include a new Serial Communication block called USCI.
These new 2xxx promise twise the power with much less current consumption. I am waiting to get one of the USB stick dev board sold at 20 bucks.
I havent looked at what USCI has to offer, but will checkout the pheripherals soon 
Cheers
