Looks like just a 'B' revision of the same scope they've sold for years... It "works" but is a mess to use, bogs down easily and will lock up periodically.
Even the B revision is old. This web
http://www.tektronixoverachiever.com/ is not new at all. Yes, MSO2000 has some advantages over my DSOX2002A. It has a bit longer memory, more triggers, better search capabilities, active probes...
But the screen is small. No pushable knobs. No TrigOut BNC. No function generator. Probably no table function for serial decoding. Well, this was decent scope in 2008.
Please note that the product videos were made in october 2012.
