The 4200U under most conditions (i.e. anything but Dolphin) runs very well actually. We got my sister a new laptop with one and it does everything she needs (web browsing + Photoshop/Illustrator) just fine. I wouldn't imagine g++ to be an issue since I've developed on weaker systems with no speed issues like when compiling and doing something else.
I have not done any Dolphin testing, but if you can wait about 24 hours, I can test a couple of games. Just specify one or two you're interested in and what Dolphin revision.
