If you are in the mood for a little nerdy story. . . Not the typical switcher story. I have been a mac user for almost 4 years now. I have been a die-hard 12" fan. I started with a 12" iBook G3 then moved on to a 12" PB and have shunned anyone for owning anything larger because it isn't really portable. Then one magical day at work (IT technician at the university I go to) I was working on a 15" windows machine (you know cleaning off viruses, spyware, all that PC stuff mac users never have to deal with) and right next to the 15" PC was my nice little 12" PB. Going from one to the other I for the first time noticed that a PC looked better than my mac for some reason! I was shocked!! Everything on the screen just seemed easier on my eyes. Then I took a step back, opened my eyes and realized that the small screen of the 12" PB was the problem! But I questioned myself, how could the small, totally awesome portable being of the 12" PB possibly have something wrong with it!!! I spent a few weeks reeling the idea over and over in my head. I even stopped by the Apple store in town to check out the new 15" PBs. Then, one day I was checking out the refurbished PBs for a good deal. I stumbled upon a 1.3GHz 15" for a good price, and decided to go for it. If all else fails I can just sell it on e-bay and stick with my 12" PB that I already have! So My 1.3GHz 15" finally came last Monday. I was questioning it at first. It seemed HUGE compared to the 12". I wondered how I would ever be able to lug it to class and to work and back again without completely killing my back!! I've been using it apprehensively for the past week and finally decided I should e-bay one of my laptops b/c it is just absurd to have two laptops when one of them just sits in the corner charging. So I pulled out my good old 12" PB to see if there was any other data on it I needed. And I was shocked! it was SOOOOO SMALLL!!!! The portability is amazing (well come on I knew this already) but its so easy to handle, sitting on the couch and such (ok, not THAT big of a deal, but noticeable) but what shocked me more was how SMALL the screen was. Wow, within a week I have totally fallen in love with the 15" screen. So in the end I sit here shocked that I am actually moving away from my die-hard 12" lifestyle and into the beauty and amazement of the 15" PB. I still cant believe myself! But I actually wish I had the new 1.67 GHz PB with the better screen resolution. But honestly, I can't justify spending the extra money just for the screen resolution. Ill wait till the second rev intel PB comes out to get a new one Until then I will enjoy my new found love of the 15" PB!!! Not as small size wise as the 12" but weight wise it is just as portable and well the benefits of the large screen outweigh the couple of extra inches of width! Jut though I would let you know if you are considering one or the other.
