We’ll start the before and after series with all the basics.

Here are the default team sites for each version.

SharePoint 2007 :

SharePoint 2010 :

What’s new :

• The landing page is called Home now.  (Don’t confuse this with your intranet home page).
• Site Actions has moved to the left.
• New edit option tags for the page.
• The Search box has been combined into one field.
• There are “I like it” and “Tag it and Notes” options, (not available in Foundation).
• View All Site Content has become All Site Content and has moved to the bottom of the Quick Launch.
• No more global navigation breadcrumbs.
• No more links to My Sites and My Links, (My Sites are on the dropdown next to your account name).
• Site Pages is new – it’s the wiki the home page is made up of, everything on it is editable.
• Sites are made up of pages, some of which you can edit, some you can’t, (called system pages).
• Announcements, Calendars and Links have been replaced with a Welcome note, Shared Documents and Getting Started – the themes section could keep you busy all day.

Verdict :

The Good :

• No more in and out of Content Editor Web Parts to modify the landing page, it’s in easy to edit wiki format.
• The online help is VASTLY better than it was!!!
• Once you get used to the new look and navigation, it’s a dream.

The Bad : No more global navigation.  Does not play well with Google Chrome.

And the Ugly : No more My Links.  This is a pity, it was a very handy, widely used tool.
