For enterprise and pro user, not need android, because app on google play not much for productivity, but if you want use for entertainment, mobile game and social media, you maybe need it if you not have android phone or iPhone
I have 2 in 1 device, toshiba satellite E45DW-C, I use it for laptop only not as tablet because I not comfort with keyboard in behind and my device so thick and weight.
Miceosoft make surface keyboard much colour and only one not have alcantara, there is black version. And why not available in surface laptop? Much people still love black colour and mee to.
They said that surface laptop is a weird device with much glue and hard to fix, can damage estetic with cut the alcantara and can't upgrade anything because all is soldered
