Just got hired by Microsoft and have already received a few raised eyebrows/"joking" references to getting rid of my iPhone...So was hoping I can get some advice/feedback on a possible switch to Windows Phone. I own a 27" iMac, 11" Macbook Air, and iPhone 5S...I love everything about mac/OSX/iOS, and the amazing synchronicity between all of my devices. I have played around with the Lumia 920/925 and they are pretty slick. I can definitely see using the phone part time (while at work) but I'm really not excited at all about totally replacing my home iMac/MacBook/iPhone culture. Here are my questions: 1) Has anyone successfully integrated a Windows phone into their current iMac/Macbook combo, and have no problems adjusting/sync'ing apps & data on both platforms (generally speaking)? 2) If I had to replace the iMac/MBA, could anyone recommend PC desktop/ultrabooks that would be closely comparable to an iMac/MBA? 3) I'm considering swapping the SIM back & forth from the iPhone to the Lumia, when coming/going to work. I already know that it can be done, but can anyone who is doing it now, comment on how difficult this transition is? Thanks for any feedback, and I'd especially love to hear from anyone who has transitioned to/from Windows Phone.
