I wanted to buy a laptop for daily usage like editing photos, videos and documents, I bought the device with these expectations in mind.I bought this notebook because apple provides great hardware and light weighted devices and retina display is a great plus for macbook pro. Battery backup is a aspect which I considered before buying the laptop.Add ons which I prefer are, apple laptops support thunderbolt ports we can connect keyboard, mouses with compatible io devices, we can connect external hardrive, projectors etc, we can connect wireless printer as a addon.
