I had a chromebook in 6th form and my first 1.5 years of uni.
It was okay. It did everything I needed - my course is very essay based so I mainly just needed Google Docs. If you're on a budget, it's not a bad option.
However, it couldn't do everything I wanted. It can't play DVDs (even with an external DVD drive), which I sometimes needed as my course involves film. Sometimes I had to find an online workaround if I couldn't download recommended software. I don't know how much software medicine involves.
When my chromebook broke, I bought a Windows laptop. It's a bit pricier and chunkier, but I never have problems with incompatible software.
