Hi, Thought i would share my 2 cents. Is anyone else sick of the QQ about the i7 and the heat of laptops in general. Facts: the new macbook air has more technology packed into its tiny metal case then most PC towers, SURPRISINGLY it may get hot, perhaps thats due to being the size of an ipad while towers have a cooler pretty much 60-70% the size of the macbook airs shell. such as the cool masters V8. if you stick all this into a case the size of an ipad it will get hot. Fact 2: laptops HAVE ALWAYS got hot under load, i remember years ago a laptop being too hot to sit on my legs when i was playing on it , since laptops began they have always got hot. Fact 3: As much as people who bought the i5 would like people to believe at how the i7 is such a marginal difference, and how many posts they make pretending they have seen the difference. if an i7 was a baby upgraded i5 it would be called an i5, i7's have always been the cream of processors. yes the 13" may not be a massive boost, however on the 11" the boost is quite large. i7's have always been a large cut above the i5's, ive used both and i7's really take the the prize every time. Fact 4: i7's have 1 mb more cache then the i5''s thats 30% more, make what you will of it but i have noticed that cache makes a massive difference in computers in general use and also using heavy use programs, games / cad / other stuff. In conclusion, i7's are a way ahead of i5's always have always will, the ghz may be smaller difference in the 13" however the cache alone 30% larger is far worth the money. also what a lot of the sites are not telling people, that the cores HD3000 on the i7 especialy on the 11" model is boosted by a far larger amount on the i7 , while the hd3000 is gimped by the i5, on the 11" i arnt too sure about the 13" finishing point: put strain on laptops they get hot, supprisingly. and honestly if i see another post about wether or not a laptop of this size can run brand new fps and other games decently im gona cry. honestly do you seriously think a laptop of these dimensions will be able to play anything on high graphics. omg seriously install a brain while your installing lion please. thats my 2 cents anyway feel much better now ahhh. if you feel the same please bump, and no i5 fanboys saying ohh but my i5 is far better then the i7 THEY BOTH GET HOT, DEAL WITH IT.
