Laptop graphics have always been something of a joke performance wise. Nvidia and AMD do try, but cramming all those millions of transistors into a low-power, compact package just leads to massive expense and an inability to upgrade.

Wouldn't it be perfect if you could simply use a standard external graphics card to power your laptop's 3D graphics?

The good news is that you can. The suitably technical-sounding PE4H is just that; a passive PCI-e x16 to x1 adaptor, which enables you to plug an external graphics card into a laptop's ExpressCard slot. Currently we're only aware of it being available from the Taiwanese firm www.hwtools.net for around $100 including shipping.

why use this when you can get a good board for that price?

It is pitch black. You are likely to be eaten by a grue.

You could but you can also get a motherboard + cpu combo in almost the same price range with less headaches. (amd brazos boards are around a hundred all this card would  save you is a cheap hdd and some ram)

You could take advantage of this by buying tons of crappy old laptops with EC slots for 10-20 bucks each, then your only cost is the graphics cards.

The problem is, that adapter costs $100. So you might just as well build a low end system and stick 1 GPU in it.

Works with any laptop as long as it has a single USB port.

I've seen old laptops with USB 2.0 ports as low as 15 dollars used. 256mb RAM, pentium processors etc.

Ok not quite an ec laptop for 20. I have to wonder if you'll hit bandwidth constraints at that point

I don't think that will work with a video card.  From the warnings in the product description, it sounds like it just passes the USB 2.0 lines from the expresscard interface.

that certainly looks interesting but you could build an entire system for less than what that costs.

Yep didn't realize they were so ridiculously expensive.

Seems pointless to create something nobody will buy because your price-point is so absurd.

Too bad the adapter is expensive, or this could have been a great idea. A cheap laptop with a weak CPU would suffice, and I would think that in general a laptop uses less electricity than a desktop.
