Would you suggest a 13" MBA + external monitor then?

Also, I'm pretty sure CAD, Solidworks and Matlab is all we run there.

I don't know if a MBA will be strong enough to run Solidworks okay or not (you will have to use bootcamp if you want to run it so make sure you have enough harddrive space win7 + solidworks probably means 40-50gb or more easy + files and other such thing fills up fast). I think I had modeling files take up 10GB flash drive easy.

13" is okay for matlab, you could probably get away with 11" but I think it would be painful.

If you want to run the CAD software like Solidworks a MBP 13" might be the better choice (256GB + 8GB RAM) comes out to cheaper than the MBA 13" equiv with upgraded proc. And could probably run it reasonably well-ish (better than MBA). You usually don't need to do a lot of model analysis in undergrad but sometimes those CAD programs can be a system hog. Especially if you get to complicated model assemblies.

If you don't want to run the CAD software the MBA 13" should be okay it just might take longer to boot up matlab but with the programs you do processing power shouldnt make that much of a difference. If you can hook up an external monitor an 11" might be fine as well.

Heres someones experience with an air and solidworks: http://solidworksonamac.com/using-solidworks-on-a-macbook-ai...

I pretty much had a change of heart during these few days, and came up with the following choices:

Asus N56JR-S4018H 15.6” FHD / i7-4700 / 12GB / 1TB / GTX760M 2GB GDDR5 / W8

and

Lenovo Y510P 5938-9550 15.6” FHD / i7-4700 / 8GB / 1TB / GT755M SLi 2GB DDR5 / W8

The price difference is a mere $6 where I'm from. I'm confident that these would do fine, even outperform the Macbooks in any way possible. However these 2 weigh a ton(almost 3kgs), and they are quite hot as well(80~90 degrees celsius for GPU/CPU, and ~50 degrees celsius surface temp, since they're plastic and all). And the build quality wouldn't even come close to Macs.

Decisions, decisions.

Those would do more than fine. If you go with lenovo they have a very good warranty with accidental damage protection for a couple hundred dollars for 3 years if you're worried about build quality (I think you have to buy from the lenovo site though).

That's good to hear. What I'm worried about is the heat and weight, less so the build quality. I'd really like my laptop to last at least 4 years, more is better, performance wise as well. Apple laptops just don't seem to hold their own after 4 years(except for the body itself, ofc).

The 13 mba when specced with 8gb/256gb is still way cheaper than the similarly specced rmbp. Does the processor matter much when talking about running cad software(and i'm aware of the retina price premium, thats why i tend to shy away from it, prefer a fhd ips external monitor).

The processor matters when you get into complicated assemblies or analysis of parts. Your school should have computers capable of running whatever you need to do and to be honest a home built computer of ~$500US would be capable of undergrad work easily.

I specced the MBA with upgraded processor which would definitely be necessary (for CAD) but even the article I linked said it was a little slow with the upgraded processor.

I personally did all my CAD work on campus and MATLAB/programming at home because of computer specs.

I think a macbook is a nicer computer choice if you don't mind doing CAD work at school, or if later down the line you decide to spend ~$500 building a computer (just the computer not monitor, keyboard, os) because working at school is a burden. Though a lot of my CAD projects were group projects, depends more on school though.

The analysis work definitely is processor heavy (I think PRO/E might use CUDA somewhat now) but it just means a slower processor will take longer to run the analysis).

Just running the CAD program usually requires an okay processor and video card but if you google around or ask on forums some other people might have better experience with running solidworks on a MBA.

Here is another experience: https://forum.solidworks.com/thread/70311

We did have some programming in basic excel formula style but that you could run in parallels or virtualbox or what have you.

I do think that Macs are nice to have and use, and that my school computers are only [i3, 4gb, 500gb] machines, some are even older. Weirdly so, there seems to be this one Tesla supercomputer in that lab that's off-limits...anyways, the rMBP is beyond my $1200 budget, more so the normal MBP specced with a 256 ssd, so I think I'll stick to Windows machines until I have more disposable income to afford one. Thanks for your input, it was helpful!

Which brings me back to my pc+tablet or laptop debate. This is starting to give me a headache.
