    Just had a chance of playing with RMBP 2.3 in store, and:

    1. screen is really perfect for reading texts, at least in apps with retina-support, eg. safari & preview. for pictures and videos, the improvement is not quite that drastic IMHO. 2. Rescaling is very handy and does not produce blur like the old gen MBPs.

    but: the whole system felt kinda sluggish! changing windows, fullscreen-mode, etc., hd-videos, etc.

    (This is *not* snappy, Apple!)

    What do you think: How much CPU/GPU power could this permanent rescaling/doubling/quadruppling/whatever eat up?

    Is there any retina-setting which could be regarded as more "energy-efficient" or, well, "less sluggish"? I heard that 1440 does not cost as much power as does 1920?! Would be a shame if much of the progress in CPU/GPU/RAM etc would be given away to the need of arranging pixels in view.

    In theory the "Best for Retina" should use the least power since it isn't doing any whole-screen scaling after it renders.

    Some users have said that the developer version of Mountain Lion has much better all around performance on the Retina MBP.
