that's integrated graphics, meaning the CPU runs the graphics not a separate (discrete) card, so forget about high level intense games, and videosmay suffer a bit. but battery life will improve.
I'm on the same boat as you here's what I'm looking for:
portability, lightweight, under 5lbs and preferably under 14 inches but not under 12. laptops under 12 inches start giving up keyboard size.
battery life, I want to stay unplugged at least 4 hours.
*non-glossy screen, my current dell inspiron is a nightmare in a library or office building cause of this glare
comfortable keyboard
wifi, if you're spending over 1000$ there's no reason it's not wireless N (otherwise it would be b/g)
3+ gigs of DDR3 RAM
I'm still on the fence about Acer. I'm not convinced about the timeline's durability, nor the fact that it has a Solo (single core) processorrather than a dual core, which will detract from performance. I'm looking at lenovo intently. a T400s would be a dream come true. look at the T400 and T500also (they are not as portable). can't go wrong with a dell XPS but if you're planning on being in the library beware of the glossy screen.
