Hi I am about to pitch an MBA 11" as my travel machine (and partly office machine) for my boss. Due to buying restrictions the 11" with 128GB is probably difficult to get approval for. We use a centralised Citrix solution, but I will need local copies of MS Office for when working at airports/trains etc. So: 1) is 64GB enough ? 2) For those of you who chose this, how do you manage so far ? 3) Is a later thirdparty SSD upgrade fata-morgana ? 4) Tips/tricks on how to use this with that limitation ? Thanks for any replies. stj.
