I need a new laptop for University and with all the student incentives I was thinking of getting a 13' MBP or MBA. I was worried however that I may be paying a premium for an OS I might not need. On my old windows laptop I used mostly: firefox Microsoft onenote excel word outlook iTunes winavi vlc media player Photoshop mathtype are there equivalents for these on a MAC? Also, I was hoping to buy from an apple store and if I chose a MBP would they have versions with an SSD HD installed? Thank you!
