I think this is the right move. The current Achilles heel of the unit is very much the battery.
A second place would be the screen — it isn’t horrible but could be a lot better. And 1280x800 isn’t exactly bleeding edge.
But 2 hour battery life is pretty bad and caps anything you could do performance-wise.
Keeping a similar performance envelope with lower power draw also takes a lot of burden from the fan and cooling mechanism, which gives you more room for battery capacity in the same form factor. That is double dipping on additional run time, which makes it a good choice to attack.
It would be nice if the resolution could bump up to at least 1080 so in-home streaming worked better and let you offload the computation in more cases. The scaling down to 800 just makes it unsuitable right now.
