Web designer on 13inch rMBP ?

[superock2]

Hi. I'm a web designer and i'm making a decision to get a 13' rMBP. I'm wondering is there any difference web design stuffs on Retina display? I have some questions about it:

1/ If i create 1170px width web, the output will be 1170px or 2340px?

2/ Do i have to zoom 200% to work?

3/ Is it pain to do Web design's works on 13' rMBP or 15' is better?

I'm a new Mac-user, so please excuse me if i have some stupid questions. I hope you can help me and thanks for reading

Hey, you need to design websites for retina anyway in this day and age. I would definitely recommend a macbook retina, but I think the 15" would be better. The one with a dGpu.
Or at least use an external 4K display, but they are not really cheap!
