Hi my experience with the Apple macbook pro 2012 version has been very good and Im very happy with the performance.
My macbook pro is a 2012 version with a i5 processor 3rd generation clocked at 2.7ghz and a ram of 4gb to enable smooth multitasking.
The laptop is gorgeous and its outer body is made of aluminium which keeps it light yet tough and durable those plastic body laptops.
My husband got this from office as a joining bonus. The laptop is amazingly fast and never faced any lags in the latest version of Yosemite which I just recently upgraded.
The OS is smooth and fast and very easy to use. I enjoy it using with my itouch 5yh generation.
The battery life is excellent with almost 10 hours on and far better than other laptops.
I would recommend apple macbook pro but its very expensive for around Rs.55000/-
