Image:What advice would you give a MAC newbie ?

Having mulled over a new laptop for a very long time I am now the proud owner of a MBP.

When I got new Windows Laptops I always imaged them so that I could roll back to a clean machine easily. I also had a list of useful software such as clipcache, acronis, winscp, putty etc..

What would you recommend I do with the MBP ?

Also any suggestions for a smart backpack and / or sleeve (15″) ?

Will the MBP really help me loose weight as demonstrated above ?

Thanks, Sean
p.s. I am mostly a developer with Linux and Windows servers
