Can I upgrade memory on these?

Hi Alex. Welcome. Unfortunately the RAM is soldered to the logic board, making a simple RAM swap upgrade impossible. The only way to upgrade the RAM is to swap out the logic board for one that has 8 GB RAM modules.

"I have a mac book air, have multiple windows open, HDR photo manipulation in Photoshop and 1080P HD movie editing with iMovie, and it never falters (in fact blows my I7 CORE desktop PC system out of the water at work).

SSD is the key, virtual memory with SSD is like having extra Ram, with instant read and write capability. Keep your drive clean, use Cloud based FREE storage systems (dropbox for example) and enjoy the speed of a fantastic PC. I never let my Mac drop below 100gb (easily done!) and it is lightening fast!

Apple does nothing for you....delivers better speed, more reliability, better infrastructure, ssd drives as a standard, lighter system, solid metal casing, multi gesture track pad, retina screen, better and faster OS system, 13 hours battery and less depreciation compared to a PC, and i will still be using the Mac long after any other PC laptop will have gone to silicone heaven, oh and they are a joy to use and super sexy. What else would you like?"

Macs: proprietary af, a couple years down the road you either upgrade your hardware or its a paperweight. A really pretty, still very capable paperweight. Put Linux on dat ##&&% and keep it movin.. AK

"To those Windows diehard whiners always accuse Apple for over price, please take a look at these links for the so called ""high end Windows laptop"" Look carefully at the prices

then compare it to the top of the line special latest Macbook Air with smilier configuration, - 8G RAM, 500G SSD, newest Intel i7 Haswell process $1850.00

And, you tell me that Apple is overpriced? And don't forget you don't have to deal with the garbage WindowsOS and the garbage wares the HP pre-installed on your brand new laptop!"
