I'm currently using a Late 2010 11" Macbook Air that was dubbed the "Ultimate" when it came out (1.6GHz Core 2 Duo, 128GB FS, 4GB RAM, GeForce 320M 256MB). I use my laptop mostly to supplement an iMac I have which is also from 2010. It's not a powerhouse or anything but I use both mostly for web browsing, downloading and viewing media, MS Office, iWork, and Adobe Acrobat. I have some heavy lifting apps like Adobe CS5 but I hardly use it because I don't know how to. I am interested in the new $1599 Retina Macbook (1.2GHz Core M, 512GB FS, 8GB RAM, Intel HD Graphics 5300). My rationale for buying a new laptop is that I have a new 4K TV that accept 4K @60fps via DisplayPort that I want to use as a monitor. My current laptop is not able to output 4K @60fps, will the new Retina Macbook be able to? Will there be a USB-C to DisplayPort adapter? Will the Core M processor and Intel 5300 in the Retina Macbook be sufficient to run the programs I usually use while crunching all of those pixels? Thanks.
