About the only visual change you'll see is if you install it onto a Windows XP computer.
Everything looks almost the same in general as the older versions on other Windows systems. Some people criticise SmartSuite for this but I think there's a lot to recommend it.
There are a couple of new features for you to get to grips with like FastSite for website creation, but in general, if you like and know Approach, 1,2,3 and Freelance, you'll be right at home from the outset.
I hope you enjoy your new SmartSuite.
Good luck with it.
