I used to have a Surface 3 4gb/128gb and the Type Cover/Pen. It was great. I did make some typos on the keyboard because of the nature of the keys being close together but it was far superior to say using a sub 10" netbook/laptop where the keys are very cramped. I learnt to type a bit slower than usual (I average 130-150wpm usually) and that improved accuracy a lot. Keyboard wasn't as good as my 11" Macbook Air (which is quite old now) but given how light/portable the whole package was and it ran Windows 10 out of the box, and it was an easy choice to recommend. I also previously had an Asus T100TA (the Transformer book) but it was crap. Keyboard was cramped, tablet itself was ugly and the display was uninspiring to use- and it had the last gen Bay Trail Intel Atom cpu compared to the Cherry Trail in the Surface 3. I chose the T100TA over the Acer Aspire Switch which was around the same price point back then - but I think there are now newer models and slightly bigger 2-in-1's for 11" (i.e. same size as Surface 3) but these are still largely plastic affairs.
That being said, despite loving the Surface 3, I sold it to buy the Surface Pro 4 (which was actually more than double the price) so I could play some more games on it and use the bigger screen, but I do miss the convenience of micro USB charging.
If you're looking to buy make sure you get student discount - from memory Microsoft was even offering 15% off if you order online from them at some point and use your uni email address.
FYI this is the Asus T100 that I used to have >
