Update my new 2013 MBA 13" to Rosemite with Win7 or not?

[Newtons Apple]

I am running Windows 7 via bootcamp on my MBAir 13" .

Would it be wise to move to Yosemite. If I did will it mess up the large bootcamp partition with Win7.

How much room does Yosemite take up as I only gave Apple 50gb of the 512GB SSD.

It should be fine, but I'd back it up via winclone just to be safe.

Dos anyone know how much space my Apple partition will be after Yosemite. I only allowed 50GB when I did the original partition.

Merry Christmas to you maflynn!
