Hi there everyone, I'm sure you get plenty of these questions each day but I would like some input. First off, Im debating about purchasing either the new Macbook Air or the new 15" Macbook Pro 2.53ghz 4 gb ram. With this said I am entering law school and will require a fairly portable notebook. Both of these notebooks are extremely lightweight, however I have yet to test the power of the new air. (Sidenote If I buy the Air I will also be purchasing the cd reader drive). Now as far as usage I would mainly be completing word processing, skype, and msn. However and this is where Im now confused due to the recent update, I enjoy playing the game SecondLife and am wondering if the Air will be able to play it reasonably well... right now I struggle with low graphics (on a 4-5 year old laptop which uses a ATI radeon x600). I noticed that both the Macbook Pro and the Air have 9400M cards and if you pay extra you can have a Macbook Pro that switches to 9600gts; is this really a big difference? One of the main differences I see is that the Pro has 2.53 ghz with 4gb ram while the Air has only 2.13 ghz with 2 gb ram. To my knowledge 2 gb of ram is more than enough for most applications currently (im not video editing). If I configured the Air, would a SSD increase the speed of the computer so that the processor gap would not seem too significant? (Considering that the speed of a computer is based upon the HD, Graphics, and Chip). Thanks!
