We have Dell laptops at work and they don't seem to last very long. Either the cosmetics start to fail (current batch has the plastic coating on the speaker grilles peeling off) or in the case of some much earlier ones we had everything bar the case failed.
However these were supposedly more consumer orientated units with faster graphics. But even so, so have pretty much every component replaced shows how poor they were.
Anyway, where would you take your Dell laptop? you would need to mail it off. I took my laptop to an Apple store and picked it up the next day.
I paid £900 for it (old stock) and therefore it wasn't so overpriced.
