Does the Chrome OS LiveCD threaten your installed OS?

How typical of google, when you install their browser in Ubuntu, its quite good, fast and stable and a great viable alternative to slower Firefox, sadly it also ruins synaptic and you have to do a hack to get the speed back or else synaptic and update hangs at 99% for a minute or more, seems like google adds a repo which is not compatible with Synaptic, it does so without any caveat, thats the sad part, when it happened to my system, I blamed slow Ubuntu repos or ppas till I found out it was Google and no one else's fault.

 

I've never had slow down in synaptic with Chrome installed, maybe I'm just lucky but it works 100% fine, and I have 5 PPA's installed as well as all the ubuntu repos enabled, as well as the opera repos, getdeb and playdeb ones.

 

On a side note, where would you get a live CD of chrome/chromium OS for testing? I have had Chromium OS for some time on a virtual box, but would love to test it with real hardware.
