MacBook Pro :: Fixing Resolution And Heat In The I5 And I7?

I have been laboring for weeks to determine which macbook pro to purchase. We are new to apple having only enjoyed the iphone and ipad. We only have used windows desktops and laptops but love the look of the macbook pro's and imacs. We want a desktop replacement laptop. We just want to move it around the home and now and then take it out somewhere so we dont care about the 15 or 17 being too big. Dont want an imac as we do want some limited mobility.

Regarding the resolution issue I am drawn to the 17 because the 1900 x 1200 looks awesome. I am not sure if I like to 1440 x 900. It seems a bit blurry and not as sharp.Dont care for the antiglare as I love the corner to corner glass look and Ill have it indoors mainly. Any thoughts or experiences with the 1900x1200 vs the 15inch options as I have only used both for a bit in the local apple store?

I have heard the i7 2.66 in the 15 and 17 pros run extremely hot, too hot to even use on your lap. Is this true because I wanted to get the i7? I have had too many windows pc laptop fry over the course of two to three years from over heating and fear putting 2k into a good looking machine that will internally melt in a couple years. If it is just a design for the heat to dissipate out from the inside to be absorbed into the unibody that is fine if that is the case. Any body know, or does anyone who has the i7 in the 15 or 17 know?

So if the heat isnt too bad in the i7 I will get it in the i7. If the i5s run much cooler I will get the i5. If it is worth the money to get the 1900x1200 resolution I will get the 17inch, if not Ill stick witht he 1440x900 or the 1650x1050 or whatever that is. Is the higher resolution nicer and is the i7 cool enough?
