I'm currently running OSX 10.3.9 on my powerbook which I intend to take to college with me. I'm an engineering major at a fairly prestigious university. I was planning on getting a new laptop sometime in the next year, but I know I want to wait for penryn and leopard (in the new macbook pro's). In the meantime, should I be fine with OSX Panther for school? I know some newer applications won't run on anything older than 10.4. I've checked the school's recommendations etc. They recommend 10.4 or higher. I just don't know if I'll really need it... Any suggestions? I really don't feel like buying it.
