Yeah doesn't look like it can decode SPI, I2C, serial etc. Personally, that's something I'd use quite a bit, but might be only available on higher priced models.

It's also 50% more expensive than the PoScope you were looking at.

IMO the PoScope "scope" is really a toy but I'm looking at it more from a professional side. I'd think I'd find it rather limiting even for personal use.
