A little while ago I reviewed Dudamobile, a mobile site building solution. Now they've launched a new product, DudaOne, which looks quite interesting - it's a new 'drag and drop' site building tool similar to the likes of Squarespace, Wix and Jimdo. The key selling points are (1) the sites created with it are responsive (meaning they'll automatically get resized to suit the device they are being viewed on) and (2) DudaOne will pull content from your existing site and populate your new DudaOne site automatically (meaning in theory at least that you won't have to upload all your content to your new site all over again).
I'm planning to have a good play with DudaOne soon and maybe write up a full review; the only thing I have to say about it for now really is that the templates I've seen look pretty strong (very 'Squarespacey'). It will be interesting to have a more in-depth look at the tool to see how its design and CMS features stack up against more established solution.
Dudaone are currently offering a 20% deal for early adopters - see link below.
