Does it have a stylus? No? Then it's not a Surface competitor.
There are lots of laptops that are cheaper than the Surface Pro series and otherwise comparable, if you aren't looking for a stylus. If you're buying a Surface Pro / Book / Laptop, it's because you want the stylus.
The stylus matters because Windows isn't really a touchscreen OS like iOS. The stylus gives you precision pointing that you can't get with a finger and Windows often requires, and it lets you hover over a button without clicking to get tool tips. The Surface screen isn't just a touchscreen, it can sense the proximity of the stylus without contact.
It's also frequently more useful than a mouse for a portable device, since you don't need a separate surface. It's not so great at right-clicking, another thing Windows wants and iOS doesn't, but overall it's a significant advantage. If a laptop doesn't have this kind of stylus support, don't bring up the Surface as a comparison.
