Hi all, My Macbook Air mid-2011 does most of what I need to do - surf the web, e-mails, music, etc. However, I'm low on storage space. Do you guys recommend I upgrade the drive to 1TB using a Transcend JetDrive or buy a new Macbook Air? While the new Macbook Airs have a faster processor and RAM max storage is only 512GB. Macbook Pro is too expensive. So based on this, I think my best option is to upgrade the SSD? 4GB seems OK - but does anyone know if this will be a limiting factor going forward?
