I am very new to this forum. My husband would like to get rid of hi PC laptop. He wants a MAC laptop because we love them. Anyhow, he needs to run the PC software that comes with his curriculum on this machine to do powerpoint presentations for his students on a screen in the classroom. He would like to walk around the classroom talking and using a bluetooth or wireless mouse to access the pages of the program he's using. We were not impressed with the MacBook Pro at accessing these PC discs. We are looking at powerbooks on ebay. We want airport at home to connect with our iMAC in the kitchen with DSL... also, we wanna be able to hook up to a hot spot, say, in Starbucks or whatever. What RAM, Hardware memory, whatever should he be looking at? thanks in advance!!!
