Why get a macbook pro over a macbook?

[blackninja]

I am in the market for a decent portable laptop - I currently have an AMD Turion dual core 1.8GHz 17" acer that I have added to by installing 4GB 667MHz ram and a 200GB 7200 seagate momentus drive (This has 2 drives in it now)

Generally, this is just fine but not always for cpu intensive stuff and I now want more portability and basic oomph I have been attracted to the macs as of late and I fail to see why the macbook pro is worth the premium for me ... am I missing something? This is what I need and bear in mind that I am thinking of getting a 2.4 GHZ macbook here:

Screen size and resolution is OK ..
4GB Ram (I have 4GB of 667 RAM already)
Fast HDD (I have the seagate momentus and I will probably get a 64GB SSD drive soon anyway)
External drive - USB 2 is OK but I currently use esata drives (the only downside that I can see)

2.4 GHz C2D with 4GB + SSD ... what bother with the Pro?

Interesting responses .. my prime use for this is to run virtual machines so I mainly want RAM and good disk speed and processing power in that order and I won't really use it much natively apart from the usual stuff (no video processing - my main rig sort of copes with that!). I think that to me the graphics/display at a premium of £400 is simply not worth it. Having lived with my Acer for 6 months now the only way that it is under spec really is in the processing department (and I want a smaller machine) - the C2D @ 2.4 GHz should sort that out!

Edit: In all honesty I think I would prefer the Pro but the cost is a factor!
