At the high end, what are some alternative laptops you would consider which are not Apple? (Preferably with full-sized arrow keys)
Pretty good laptop, the screen is great even, colour-calibrated 2880×1800 IPS configurable to 60 Hz refresh rate. However, the up/down arrow keys are not full size, their height is smaller.
Edit: Just noticed the full sized arrow keys part, don't think Thinkpads have that.
