Hey guys i just joined the forum a few days ago, i joined to see if i could possibly get some help in making a decision, as of rite now i use an hp dv5, i have always used windows but i have decided to make the move to a mac. I love my current computer but recently the DC port messed up and i had to pay $200 to get that fixed, thats a lot of money for a college student like me and now that thats fixed the battery wont charge anymore i'm not sure if i need a new battery or if its the power supply but either way i will have to spend at least another $100 bucks😱. So i have pretty much made my decision to switch to mac and sell this laptop off, mainly because i know that my initial problem wont happen with a mac and the mag safe charger as it did with my current laptop, and also because i have lately been using os x at my uni's library and with my roommates laptop and i honestly prefer it from windows vista, i have never used windows 7 but it seems very similar to vista so ill stick with os x. Now to my main question which mac would suite me best? i will mainly be using it for regular school work (word processing, and power points), along with some e-mail, web browsing, i will be using iTunes a lot and most likely a photo editing software such as Photoshop or maybe the new aperture since i will be buying a digital SLR sometime this year too. I really think the low end 13 mbp can handle all this but what would you guys recommend me or what kind of configuration. I also want to make this a long term investment, i have only owned my hp dv5 for 1.5 yrs, i would like the mac to last me at least 3 yrs. 
sorry if im asking too many questions lol and thanks in advance to whoever answers them.
