It's only been a year, but it's hard to categorize this deal as anything but a complete train wreck. The price tag for Autonomy –- a whopping $10.3 billion -- was widely criticized at the time by both media and analysts as well as competitors like Oracle's Larry Ellison (pictured). But the wheels came off in a big way this week as HP took an $8.8 billion charge for the software company and claimed Autonomy's management used "accounting improprieties" to inflate the company's value. To top it all off, HP has sent the case to the U.S. Securities and Exchange Commission's Enforcement Division, which could lead to a civil and criminal investigation. If that's not one of the worst scenarios for an acquisition, we're not sure what is.
