It's also no wonder sales are slowing down. The Surface Pro 4 came out in 2015, and while it's a capable machine, you can easily find better hardware from other computer makers. It's also been two years since it updated the low-end Surface 3. While the Surface Book was an exciting addition to the Surface family, it also launched with a slew of problems, and didn't sell as well as Microsoft had hoped. At least you can get one with some vaguely modern hardware, though.

We're gearing up for an education-focused Microsoft event on Tuesday, May 3rd, where the company might finally unveil the next entry in the Surface lineup. And if not then, we might also hear something at its Build event next month. Given that Microsoft helped make the dream of tablet-like laptops a reality, I don't expect it to give up on this category anytime soon.
