Just like everyone else I've waited for MBP update for so long! Now finally MBP is updated but I'm not so happy update for 13'' because that's what I was planning to buy. Now I am really confused between the 13'' and 15''... I am a PC user and I've never used a mac before...so I dont know much about apple laptops.... Can you guys pleaseee help me decide which MBP is worth buying?????? Thanks!
