Sometimes people are just comparing i5 vs i5 without considering WHICH i5 they're comparing.
Yeah, until I started looking into buying a laptop I never realised the sheer number of various wattage CPU's Intel has on the market. The fact that they stick with the i-series nomenclature across the range is clearly very confusing. They should put some indication/benchmark representing the performance on these devices. Like how car manufacturers do for engines (bhp/torque) as simply stating the engine capacity is largely meaningless given the small turbocharged engines on the market today.
One question I wanted to ask is did you try connecting the Macbook Pro 13" to an external display and, if so, did it work without issue as I use my laptop connected to an external monitor about 2/3rds of the time.
