Robin,

I don't have time to provide you with the level of detail you're asking for above (ironically), but some bullets:

-I had skipped 50-2, so I have no direct experience with it, sorry
-By first statement I meant first statement that I quoted
-Referring to bug reports is essentially an offhand explanation of problems IMO, but I won't argue that point
-Given that some are not experiencing those bugs, I would think some of us can help you. Often bugs do not manifest in a vacuum but have underlying, and commonly hidden, causal factors

I understand you are trying to tell the story for you and on behalf of others, but you must understand yourself that your approach can lead to entrenchment by those who have seen the opposite of your experience. Asking for help from those reporting a better experience than yours works much better here than tossing out blanket statements of unusability.

I won't deny you your frustration, especially given that I guarantee you mine has been much higher than that of most here due to my direct (prior) involvement with the tablet program. Just suggesting you try another tack.
