University computer, because want to learn video processing and editing, and software such as Ps Ae system Pr, so the computer.

1. About AE, these computers you mentioned are not stuck for beginners as long as they don't need too much memory for special effects. For those who like all kinds of tossing, don't talk about these computers, no matter how powerful they are, they can be stuck.

MacBook, Air or PRO, first of all, you have to be able to use OS X.

2. With regard to PR, it is not a big problem not to color, add effects or edit more than 720P. Is nothing more than the final output speed. Notebooks don't expect hard disk memory CPU to be comparable to desktop computers.

3. Regarding PS, this requirement is much lower, but so is the notebook screen.

The above is nonsense about bedding.

Then tell me the three computers you chose:

1 model. ThinkPad T550,7000 or so, I5 fifth generation processor, 940M low-end graphics card;

2. Lenovo Y430pAT-IFI I and I5 four-generation processors with GTX850M high-end graphics card;

3. Apple's Air, Intel GMA HD 4000 nuclear display can't even compare with 940M, so it's miserable to look at the hardware only. Only the display has some advantages, and then the OS X system and portability, but that's all. It is better to do PS, AE, PR and push forward in front of customers. If you talk nonsense with air, it's impossible. In addition, editing with OS X is not as good as using MAC PRO and Final Cut Pro.

So you have to understand that whether you want performance or portability, the performance is not as good as that of a desktop, and portability does not expect to use a 7000 notebook as an AE card.
