The Vostro is a budget business line of laptops for Dell. It's a cheaper option when compared to a Latitude. It's more utilitarian and subdued then the consumer line Inspiron with its black chassis and fewer curves.I will agree with that. I am surprised that the Studio 17 doesn't have the same GFX card option as the MBP of similar size.
And contrary to popular belief, Apple Care is a very good deal. I have fixed many a cosmetic problem/flaw on my MBP for free in less than two days.
I don't see any problem with Apple charging a premium for the Macbook Pro if it can really bring professional features that the majority of other laptop makers are offering. The 15" model could stand for a slight price reduction to say $1,899 retail.
The disparity is very noticeable on the 17" model when compared to other 17" notebooks. You'll notice that most other 17" laptops are a little thicker (1.5" gasp!) but you get port replication galore, gamer/enthusiast video cards, full sized keyboard, and dual hard drives.
The only thing you need is a low end video card in the MacBook and Apple can have all its fun with the Pro. Currently a ATi 3450 or an nVidia GeForce 9300M G. Sure they're low end 64-bit interface and shader limited cards but they're better then what Intel integrated offers today!
A mainstream laptop that costs more then US$1,000 should not have integrated graphics .
