The cool thing about it is that it provides complex triggering, and directly decodes CAN, I2C, SPI, and RS232 data streams.
The whole thing easily fits in a pocket, which is hard to beat for on-the-go or cluttered bench jobs.
From Tom Le Mense: Here are my comments regarding the USB logic analyzer.
I have one of the original DSO Nano scopes and find it quite useful.
The V2 is a wholly reworked version and includes a signal generator.
