This whole two machine for students jazz is garbage (kinda).
Well i guess it does depend on what type of student you are...
I am a medical student and the MBA fits all of my needs (email/research/chatting/iphoto/MSoffice).
Majority of students (med/law/dent/most undergrads) would use only those functions and would have no need for a second machine.
Just my thoughts....
I am an engineering student, and I need to run Microwave Office, Maple 11, MATLAB, Metroweks CodeWarrior, Cadence PSPICE, and AutoCAD on a regular basis.
Most of the files associated with the above mentioned programs take up a lot of resources.
An adequately powered single machine would be enough to get the job done. But if a student chooses to get a MBA, I highly doubt that it will be able to provide enough juice to handle all of the mentioned software. As a result, they will need an extra machine- or at least an external HDD, defeating the purpose of getting a MBA.
Therefore, I do not believe that the whole two machine for students jazz is "garbage".
Please do note that these are my own opinions which could differ from consensus.
