It's funny how back in 2005, IBM sells their PC/server division to Lenovo. Lenovo is currently the largest PC maker. During this time Dell has been bought and sold and re-bought.
And the value of Dell's business isn't in selling PCs, it's in other services around the PC.
Since ~2005 they have ~5x'ed their revenue. Which is pretty significant if you consider one of IBM's big problems has been declining revenue. Proving the problem with the business wasn't the business itself but IBM management.

Unfortunately for Dell, anyone can make a PC.
