So the new MB's are coming this Tuesday and from the rumoured photographs we've all seen, the casing is entirely sealed, meaning you're not going to have easy access to the battery or RAM. The implications of this are that I guess you'll need to get handy with a screw driver if you want to update these things...but here's where the interesting thing is. The MBA in its sealed case has its RAM soldered to its circuit board, its not updateable. What are the chances that the RAM will also be soldered to the circuit boards on the new MBP's and MB's? Are we all going to have to buy full amounts of RAM on tuesday or will we still be able to buy third party stuff and fit it ourselves?
