If reports are to be believed, Microsoft might be in the process of expanding this brand to another PC form factor. Microsoft is reportedly going to launch a Surface-branded all-in-one PC late next month.
I agree it is kind of late to release a All-in-one PC or desktop PC now that almost everyone owns a PC which they bought from HP, Asus, Dell Lenovo, and other brands. Plus, more people are building their own computers to save money, and have better performance without spending a lot of money on a pre-built PC which is usually more expensive.
