Now build up the E5610 so it has comparable options as the MBP. Stock it doesn't come anywhere close. Resolution too low, smaller hard drive, less ram, crappy Intel GPU, no bluetooth, no backlit keyboard, crappier CPU.Are you sure that the Macbook Pro uses a an IPS panel? They typically have not.
The Latitude E6510 currently is currently on sale for $1399; a typical Dell sale. I think a notebook with comparable specs and build quality can be found for close to half the price as the Macbook Pro.
I honestly believe I could find examples where Mac hardware is over twice as much as a similar product from another company, but don't have the inclination to do so right now.
But you are right I was mistaken about the IPS. It seems the MBP's as of yet still use TN panels.
