is 256 GB enough for engineering student- solidwork,autocad etc no (dual boot as wel)

Well if you are taking computer science I think you will have to use Windows at some point during your studies. So you will need to run Windows in a VM or natively using Boot Camp. You will need to use several programming IDEs, most of which are Windows only.

I've owned two Lenovo computers and one when it was still called the IBM ThinkPad. Of all the computers I've owned, and I've owned many, the Lenovo's had the best keyboards, IMO. But they had the worst displays. All of them suffered display failure within three years. One I dropped at the airport so I did not count that one.

I have a Lenovo running here beside me as I type this on my rMBP. The Lenovo has been running Linux, with an external monitor since the Lenovo display stopped working some time ago. It is running Linux 24/7/365 and I never have any issues with it.

I also have two MBPs. One is a rMBP. I have no problems with either. I run Windows for work on both my 13" and my rMBP and Windows performs well on both.

I don't disagree at all. This involves more than just programming. When you submit any assignment, you need to make sure it works in the environment where it will be assessed by the professor. If the professor is going to test it on Windows, you should too. That being said, the best platform for running multiple environments is a Mac. You can write and debug your software on the Mac, test it on Windows, compose your lab report in true-blue Microsoft Word, and run a huge array of open source software without having to edit your Mac's config files with a text editor.
