I am planning to get my first ever apple laptop, and i have decided to go for the macbook air 13inch, i5~~ I read that it would be best for me to upgrade to the 8gb ram. However, i went to the store nearby and the employee told me that they cannot change the 4gb ram to the 8gb ram for the 128gb 13inch. I know i can configure it this way if i order my MBA online but there're 2 stores nearby so i'd prefer going down and getting it myself. Also, i am intending to use this MBA as my primary computer and i want it to last me for at least 4 years, so should i get the 256gb SSD instead? Is it worth the money considering how i know that i wouldn't need that much space now but i'm worried that my needs might grow and we can't upgrade the SSD for the 2012 MBA in future just yet, can we? Finally...if i were to get the 256gb SSD, can the employee in the store actually help me upgrade to the 8gb ram? If he can't, then will getting the 4gb ram affect me after a couple of years? Or should i just order online instead? Sorry if i wrote too much, but i hope you guys can read this and help me, a future macbook air user... i will mainly be doing work, chatting, music, movies, running some apps at times but i don't game or run heavy-duty apps much if that helps.
