But on the flip side, as a gamer, I couldn't imagine giving up my discrete graphics cards on my gaming desktop. How many years back and how low resolution and graphics settings do you have to go before you find a game which is playable on an integrated chip? I guess it depends a lot on your definition of "playable", and your game selection; if GOG is where you regularly buy games then the integrated chip is probably more than adequate. Or if you're using a single 800x600 monitor, you're probably ready to run the latest games on your integrated chip. But otherwise, I can't seriously recommend anyone play games on an integrated video chip.
Sidenote: I would choose the touchpad as my #1 source of hardware frustration. Anecdotally, I haven't had much issue with graphics cards, other than one replaced under warranty.
