Once upon a time integrated graphics was the cheapest way to get pictures on your screen.
Memory was expensive and a separate card just for graphics with its own ram stuck significant £££ on to the price of a computer. On the downside it was stealing memory from your programs to use and slowing things down.
These days technology has changed allot both hardware and software. Integrated graphics is very well planned out, rather than just a budget option. The increase in laptop popularity has helped as well everything is integrated more or less, so huge leaps have been made.
So, Integrated graphics bad? No! I currently love it, I have a fab little mini sat on my desk quietly doing its job. rather than a huge power hungry behemoth on the floor.
Unless you plan on seriously intensive games, or work in some lab, modelling complex fluid dynamics around the latest oil-rig that you have just designed... then I suspect integrated will be just fine.
