Ive booted the latest Ubuntu OS off my memory stick and Ive been running it for a day and I am pretty impressed. Compared to how windows used to run on my laptop (as well as it being slower as reading from a memory stick)
What I would like to know is anyone who uses it how they find it in the long run getting used to it and program compatibility etc
If all seems well i'm going to do a full install so would like to know

Thanks in advance
By latest I hope you mean the not long released 10.04 :approve:
I am upgrading my system to it as we speak so I will let you know my thoughts on it.. they changed it to apple mac style window buttons (on the left instead of right) so that might take some getting used to.
Boot times are getting crazy... my laptop would boot Windows XP in about a minute, the same laptop boots ubuntu 9.10 in under 7 seconds and never crashes.
10.04 they have increased the efficiency of bootup even further, give it a go if you haven't already although check for any known bugs beforehand as it's just been released, I know of a few potential show stoppers depending on hardware.
A few days, some bloke at Scottish power decided to cut the mains going to my company, the UPS's kicked in and saved the servers but I had to go in to get it all back up and running properly.
After 15 minutes all Linux systems were fully booted and running sweet, 2 hours and 45 minutes after that I had the Windows systems running acceptably !! says it all really !
Have fun and if you get stuck on anything give me a shout !
