Hi
We are setting up an all fresh SharePoint environment, no SP migrations, no SP legacy and I was reading up on the SP2013 new ‘app’ model. My first thought was(is), OK we do all our customization via Apps, no need to use the ‘old’ way of workingÂ
Of course I’m not well placed (yet) to decide on the ‘no need’, hence this question to  people who actually do know what they’re talking about :Â
– Why would we want to invest/develop in webparts (full and/or sandboxed) ?
thanks again
Danny
Hi Danny
I will get Jesper to comment, I know he has recent personal experience of the App Model (along with all its wonders ;)).
