I agree. There's nothing in particular that separates an MBP from its competitors, aside from maybe battery life (?) and of course, the operating system.
I mean, yes, it's a big slab of aluminum that makes it look different from the majority of other similar laptops, but I personally don't like the look. I guess the aluminum is fine, but the overall design isn't particularly anything to get excited about (especially since it's fairly played out). At least with the MacBook Air, it's sleek and sexy... same with the iPad and iPhone. The Mini and iMac look very classy. But the MBP? Not my cup of tea, weirdly.
I also think it weights a lot... not that I'm weak, but its deceiving with its footprint I would say.
To each their own though!
