So I've been lurking on these forums for months and call me crazy but I think a lot of you are very well informed and knowledgable about mac and pc products. I am graduating soon and will be getting a new laptop to replace my 14" Dell pos. I will become a teacher so most schools use macs and I can get an ed discount. However I never really use a mac too much and learnig a new OS does not really make me too excited. I could load windows 7 on it though. My question is should I go with a mbp or a windows machine. 13" is the size I want and I want it to last me a few years. I am really dissapointed in the c2d with the 13's. I will be using the laptop to grade papers, manage a website, photoedit, create documents in word, lessons on ppt, stream video, web surfing mild gaming etc. Nothing too serious but I want it to last me 4-5 years. My experience with windows pcs tells me machines slow down over time. So the c2d right now is great. But 2-3 years from now can I expect a machine that doesn't feel snappy and fast? Also is iLife really that awesome for a guy who just started using a dslr and loves it and wants to start his own blog?
