Well I've been giving it a trial on DVD not installing so far, mainly because in the past this has not gone all that well for me. As to the Live trial, I was pleasantly surprised as I installed in memory restricted extras and gave the dash search and preview a walk round the block and was quite happy with it.
I then thought it would be a good Idea to try it from a Pen drive, I had a spare 4GB one so I thought it should be straight forward, no such luck. I just can't get it to boot from USB it copies but won't boot I tried copying using startup disk in 11.04 and 12.04. I thought it would be usefull to test it further but installing a number of packages and saving the settings on the USB.
I did note that there was no right click on the desktop and everything went through the dash.
Is this a known USB problem with Ringtail, I had a look round and found others with the same problem.
