I will be ordering the i3 and the keyboard/cover for it right after the first of August. That particular model, in my opinion, will probably not sell as fast as the others and should have no problem on a backorder. Since it is the lowest performer of the bunch, there should be no 'clocking' of it.
But, I will say this; if I have even one problem from that tablet, it will be wiped out and will become a Linux machine!
I already put up with about 5 months of down time with the RT because of the WiFi (which works perfect now) and I will not tolerate that again.
The more I see of issues with the tablets and also comparing those issues with laptops and desktops, I do believe that the whole problem is not the drivers but the operating system itself. Memory leaks could be the cause of these issues interfering with the drivers.
That is a guess and no proof of it. But I have seen a few similar issues when working on laptops and a few desktops that people brought to be worked on.
I think the operating system itself is the problem.
