Apple Mac 13'' for basic previewing & cutting out in the field?

Is anyone using an Apple Mac 13 inch for basic previewing & cutting out in the field. I'm looking for a new Mac laptop and I'm wondering if the 13-inch MacBook Pro with Retina display will do for basic capturing out in the field and previewing. These are the specs
13-inch MacBook Pro with Retina display

• 2.9GHz Dual-core Intel Core i5, Turbo Boost up to 3.3GHz
• 8GB 1866MHz LPDDR3 SDRAM
• 512GB PCIe-based Flash Storage
• Intel Iris Graphics 6100

I know the 15'' would be better however keeping costs down is important. Any advice would be great
