I currently have a Nokia Lumia 1020. I am about to purchase a new iMac that will be for work/personal use. Also this will be my FIRST Apple / Mac OSX computer. Finally making the switch & EXTREMELY excited, anxious and sadly nervous... I have currently have my Lumia 1020, A Lenovo Laptop w/ Windows 8, and a Xbox One. Now everything in my Microsoft "Eco-System" works together flawlessly. Between my PC & Xbox with SmartGlass to taking 41MP photos and seeing them on my SkyDrive on my Xbox or PC. I feel an iMac would disrupt everything. One thing that is a main concern is that im subscribed to Xbox Music & I love it. Being able to listen to anything and download unlimited songs to my actual storage on my Lumia is awesome. Also Windows 8 has an Xbox Music App/Tile to stream. I also have seen the cool things in Mavericks such as sending directions from your computer to your phone, iBooks and more. Which obviously you can't send it to WP. I also don't think there is a way to sync my photos if I got an iPhone to my SkyDrive (automatic uploading) so I can view on my Xbox but that wouldn't be a huge thing. Also iOS has SmartGlass which I love to use. I have had iPhones before & I would easily get an iPhone 6 when released. The one main thing holding me back is not being able to download songs to my phone from Xbox Music. I know there is an app but it only offers offline listening for playlist. I would love to go convert fully but I feel everything would mess up. Let me know what you think.
