I disagree with the point about graphics as even though the programs may become more graphic intensive it won't seriously affect the performance of the laptop, for tasks that the OP is listing, and so long as the laptop is not used for graphic intensive purposes then there is no real issue. The slowness is can also be taken account by bad maintenance of the computer, often just reinstalling the OS will increase it's speed.
That's what everyone always says. People usually find a way to defy this. Trivially the other stuff.As I said on both I'd be looking into the warranties.
