When you look at the best laptops you can buy today, you’ll see a few different form factors to choose from. You can buy a typical clamshell laptop if you just want the basics, or go with a tablet and a detachable keyboard if portability is your number one priority. But then there’s the best form factor a PC can have — personally speaking, at least — the convertible. Convertible PCs give you the versatility of a tablet while also having the convenience of a keyboard permanently available, plus they can usually afford to be more powerful than a typical tablet.
