I'm in the market for a laptop, and I'm wanting to switch from PC to Mac. I have an iPhone 4s and an iPad 2. It seems that the logical direction would be to go with Mac since I have Apple mobile devices. My main dilemma is that I'm trying to find something in the $500-$600 range, and that limits me a lot. What I'm looking for is, what do I need to know before making a purchase? Here's what I DO know: 1. I need something with at least an intel core duo processor (is this the newest?) 2. I'd like at least 2 GIGs of RAM. 3. Hard Drive space needs to be around 300 Gigs. 4. I need at least Lion to get all the benefits of iCloud and syncing all devices (is this correct? What else do I need to consider? thanks in advance for any help you all can provide!
