By the way, since we were speaking about how bulky and heavy the Surface line was compared to iPads yesterday, the iPad Pro is 713 gramms vs. the 800 gramms of the SP3 and the 620 of the S3.
Hardly an earth shattering difference and you would expect that the SP4 will be a bit lighter than the 3.
I'm still not sure how exactly the iPad can be seriously used professionally. Surely nobody thinks that it can replace a laptop?
I don't think the SP4 will be much lighter (not that the difference is anything meaningful). Has to use the same docks, large battery (if its still using i3/5/7 processors), fan etc.
I also don't think anyone is saying it can replace your laptop, mostly because apple has not marketed it that way (in contrast to MS).
What's hilarious is in the iPAd Pro thread, people are discounting the Surface Pro as competition because the stylus doesn't have pressure sensitivity.
What would be interesting is the performance comparison...i thought the i5/7s were well ahead of ARM processors, but apple has been doubling CPU power every year vs 10% for intel.
EDIT: Looking at anandtech benchmarks, if the iPad Pro is 4 times quicker than the Air 1 (2 generations) then it looks like the performance is a notch below the Pro 3 and in-line with Pro 1 performance. The Pro 4 is rumoured to get a 2 generation bump in cpu though.
