First time poster, but here is what I was told:
From a reseller I inquired (Digital Spyders).
|Acer misrepresented on their web site when they say the notebooks are customizable. Only in rare occasions when they make a change in a notebook, but you have order over 500 notebooks. We have control over the memory, where we can add extra but can’t take back the memory that comes with it. 512MB is plenty for pretty much any application out there.|
