Got this from Adwords recently, looks like they are looking to wow people into buying in. I personally have not found a lot of response from Adwords, but it really hard to say since no one clearly says well I came here from an Ad.
In the coming weeks, we'll upgrade your AdWords account to a new web interface designed to make campaign management faster and easier. You can try it now; log into your account to use the new interface immediately.
You'll have at least 30 days from the date of this email before you'll be required to use the new interface to manage your campaigns. During this time we'll continue to release additional features and make adjustments to the new interface based on advertiser feedback.
We're working to ensure that the new interface contains all of the reports and controls you need to manage your campaigns effectively. We won't upgrade your AdWords account to the new interface until we're confident that it will meet your advertising needs.
Before we upgrade your account, you can switch between the new and previous interfaces at any time. Click the "Previous Interface" and "New Interface (Beta)" links in the top corner of your account (Next to your email address) to switch back and forth.
