Ok, so I currently have a Sony VAIO vgn-fw140e laptop... it's pretty good, better than my actual home computer which died like 3 weeks ago after just 3 years use. Well I've had this laptop for just 2 years, it works and all but it's not as fast as i want it to be. It just has 3gbs of ram and 2.27ghz with a 230gb HD. I like to do powerful stuff with my laptop like edit movies with Pinnacle Studio and all that but sometimes my computer lags to much, I have to wait like 5 minutes from the point i push start up and the point i want to start up a program like Firefox. Now, I went to Bestbuy and Played with the MacBooks and Macs. They're extremly fast compared to my Sony laptop. So i'm thinking that i want to upgrade to a MacBook pro, the 15 or 13 inch one because of it being fast and "powerful". But i'm not sure if it's worth the money. Is it worth to buy a MacBook Pro?
