Haswell isn't going to be some miracle. It will be a larger upgrade than IB was but nothing earth shattering. It will be faster, cooler, and more power efficient. Nothing so big that new apps won't be able to run on IB hardware, that kind of change will never happen from one year to the next. They are saying that Haswell is going to be out Aprilish next year so probably early summer for the new computers and that's assuming that it's not delayed which is a very very real possibility. If you need a new computer now, get one. If you don't, wait. Personally I would wait if you don't need one. Getting the first model of a completely new model anything is generally a bad idea.
Intel IGP's rock. They aren't the most powerful thing in the world but can certainly get the job done. With the ability to play 1080P video it has eliminated the need for a discrete GPU for a large percentage of the population. Most people use computer for Facebook, email, and videos. Professionals and gamers that need a discrete GPU know they do but in general the masses don't. With Intels new GPU the masses are saving a lot of heat, battery power, and noise. I give props to Intel for how far they've come with them since they started making it a focus a couple years ago.
