There are now 3 different choice, with both pros and cons on each of them:
1. 15" 1920x1080
- Pros: large resolution
- Cons: text will become very small if screen size is small
- Cons: laptop GPU need to be above-average, so that it won't lag/lower details when performing GPU intensive task (such as gaming)
2. 15" 1366x768
- Pros: Balance build
- Cons: balance build = nothing special
3. 14" 1366x768
- Pros: sharper details compare to (2)
- Cons: screen size small
I prefer 2. 15" on laptop is just nice.
