It depends what you want to use your MBP for. If you need the extra power and your workflow requires a bigger display, then the 15" is still the better choice. If your workflow gets better by having a second screen and you don't need the extra graphics card power, then the combination of a 13" Macbook Pro and an iPad is nice. It all depends on what your requirements are. I have the 13" MacBook Pro and I personally find the iPad not very much useful, especially when I consider that I can use my MBP for most tasks the iPad can do. I don't need signing documents or working with PDF files and a pen, so I don't need an iPad. For content consumption the 13" MBP is great, and is extremely mobile too, so for me having the smaller MacBook Pro made my iPad unnecessary
