My gf has an iPhone 4S and pays with prepaid Walmart cards for $45 a month. However, the Project Fi network would seem to be cheaper alternative for her. And now the Nexus 5X is super cheap for only $200 with the Fi deal. I have a Nexus 6P and I love it and I heard the 5X is similar. So now I have some questions/concerns...

• How does the 5X differ from the 6P? Is there any features this phone severely lacks to not be an "all around phone"?

• She has a 16 GB iPhone and has enough space. Is 16GB storage enough to suffice on this phone or is the extra 50 dollars worth it?

• How is Project Fi? If anyone has used it in Arizona, their experience would be appreciated.

• This may come off as sexist, but are there any women who have used this phone on this sub? How do you like it? Apologies if this comes off as offensive.

• What is your absolute favorite selling point about this phone?

Thank you so much!
