Hi,
realized I haven't replied to your question...
yes, it's easier with sourcetree to work.
-- it's easier to share work, and work as a team
-- It's easier to have proper history of what you did, and revert a file for example
-- It's totally fail safe, you will never loose your work ( harddisk failure, lost dvd, dropbox folder deleted, etc,etc) full stop...
Bye,
Jean
