Actually, one thing I forgot to mention, which I feel IS a magical eye-opener is the multi-touch trackpad. That thing works so beautifully well, it is a joy to use. Once you get used to all of the gestures for scrolling, right clicking swiping forward/back, switching apps, you ask yourself WHY HASN'T ANYBODY THOUGHT OF THIS BEFORE?!?!?! It is such a superior user experience, it's not even funny. It has practically wrecked me for using any other old style trackpad..
I have to really really agree here.
I liked it as soon as I saw it. Was jealous of it (I had a 2007 Macbook before this MBP I have now) but never could find a reason to upgrade (they barely gave me a reason this time but after wanting a new laptop for years with the light up keyboard and the multi touch trackpad, I finally caved and got one) spec wise (and I'm on a budget, I can't really afford to buy a laptop just to find I wasted the money so couldn't just buy it to see if it was worth it).
I have to say... I hate using old macbooks now with the older style trackpads. The trackpad is as awesome as I thought it would be (you have so much room to move the mouse around adn gestures are awesome). I had just gotten a magic mouse for christmas that I was taking with me everywhere cause it was so much nicer than my macbook's trackpad. I no longer feel the need anymore (I only use it when my MBP is hooked up like a desktop).
As well as the 10 hour battery (I love that too). And the RAM (it has more than my old one could even max out at). Those are the big three reasons I don't feel I wasted my money. I know, small sounding really for 1200 dollars, but they really make a big difference in use.
These are all specs that people tend to overlook when just comparing specs and saying you could get a PC for less (particularly when we're talkign laptops where you don't really get to piece together what you want but have to take the case/keyboard/trackpad they give you).
Sure, honestly, my macbook wans't that much slower than my MBP (though it had a lot of lag, having 4x as much RAM really makes a difference). But the small things, the case (even more small and compact and lighter than my macbook and my macbook wasn't that thick in the first place), the trackpad, the light up keyboard, 10 hour battery, all add up to a much nicer experience.
Don't discount the design features, they really can matter when it comes to actually using hte product.
