Need to replace an aging PC. Intrigued with the idea of getting a 13 inch rMBP (8GB Memory, 256 SSD) to run connected to a monitor in clamshell mode and still be able to be portable in the house or outside of it instead of a standalone iMac or mini. Primary uses include: - Family computer - Productivity apps (office) - Lightroom - iMovie - iTunes - Plex server for streaming to TV - Lighter kids games Also thinking that it is best to put the data on a NAS drive so I can have access to it all throughout the house and other computers. Any concerns that I should be aware of? Thanks.
