So I'm over due for a macbook. I was originally going to go with an Air but I sometimes need a little bit more juice than can be fit into that small package right now unfortunately. I like the 13" as it is very mobile, yet not too small for regular use. My question is this: What has happend in the past when apple announces the new line and before the actual release? My concern is that they will discontinue the 13" as some rumored have stated. If that does happen then I will just snag a 13" as soon as they announce the new line (assuming this all happens in the next 2 months). I would also preferably like to customize the laptop (change memory and storage). So, I would like to know if you were able to modify the devices post announcement in the past. Modify them like the site allows you to now. Thanks in advance from anyone who might remember anything!
