Even with a fully unlocked enterprise license on it, autocomplete was lagging far behind me on a high end macbook pro. Maybe I just type too fast or the libraries I use are poorly laid out, but it was not working.
I recently fired up WebStorm and found typing to be slower than atom for most files. I wouldn't open a large file in atom, sure, but it's been getting better in that regard and generally most of my code files are < 400 lines anyway.
