So I'm over due for a macbook. I like the 13" macbook pro as it is very mobile, yet not too small for regular use and has more kick than an MBA . My question is this: What has happened 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. 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!
