How thoughtful of them. 
As a current nexus 5 user, mac user and former iPhone user with 70% of friends using Android now here is were I stand.
Switching to iphone pros:
It's finally nice to have larger screen options on iPhones.
Should have a better camera and photos app.
It's nice to see Apple loosening up on the walled garden but still have ways to go.
iPhones always have great build quality and at least up to the iphone 4 seemed to have better/more accurate touch. Have always liked the accuracy of the iphone keyboard.
Reasons not to make the switch:
I mostly use non Apple apps since they need to be cross platform or I prefer them. ie Hangouts, Mailbox, Google Maps, Google drive (more free GB's), Google Play Music All Access, Chrome prefer the mac version of chrome because safari doesn't have the website logos so I can quickly pick out a tab so it's nice to have mobile and desktop sync. (Beats doesn't exist in Canada and GPM is cheaper $7.99 a month)
Can customize the look of Android and not iOs unless you can jailbreak. iOs just more closed in general.
Don't like the look of the bright white iOs menus and bright pastel coloured icons.
I like the look of Android L. Looks clean and grown up big step forward aesthetically for Android we'll see about functionally.
Spending $1000 on an iPhone. I'd want to get the plus 64gb and with my plan I can't get it at a subsidized price.
My nexus 5 is still a very capable phone.
I'll definitely be holding off until L and the Nexus 6 comes out and try and play with an iphone 6 and plus to compare.
