Hey Smibbity - sorry to hear about your negative experience.
Have you had any Pro Tools training? Such as the Digi courses, 101, 110 or 201? They are only a few days and can really help getting up to speed on a system you don't normally use.
Regarding your issues:
1. Im not sure why you would want to do this? Its not a frequent feature request over here. Can you explain a bit more or post a video of what you are trying to achieve?
2.Region layers are a bit odd at times - they are however well explained in the reference guide - simply search for "layer" in the pdf (help menu link) and you should find plenty of info
2b..Very handy shortcut for this, particularly with plug in automation, hold Ctrl+Cmd+click on the parameter you wish to see and your track view jumps straight there, no need to use the lengthy menu
3. I haven't used DP, but you're describing features that are definately on the list "To do" when resources and time permits. Being able to see both the waveform of the region under and the one you are moving will be very nice when we get there. Until then, "Sync points" and your grabber modifier keys are the fastest way to position things quickly
4. Yup - known issue and a feature request I've heard a few times. "N" key when in keyboard focus mode changes playback position from where you left your cursor to where you stopped playback, helpful tip that's partially related. Also the arrow keys move your window view to the start or end of your selection, also handy
5. Can't say Ive ever been frightened by it myself - different workstations have different architectures that in turn beget different strengths and weakness. I think the strengths of PT outnumber the weaknesses given how many people get their jobs done on time (and well eg academy award style) using our platform.
6. Is a debatable topic definately! I was the Pyramix product specialist over here for awhile and they have very customisable keyboard layouts, but to be honest I never got into them. The company line from Digi on not turning on anything like that is that one of our key strengths is that every PT system drives the same and it creates a type of community for folks to share shortcuts - just like this one.
Next section - no latency in LE? Sorry? I'm not sure what you are specifically referring to here, but Ive definately had LE systems with massive delays from note engage to note playback without tweaking the playback engine settings, just like on HD or any other native system
2. Priority is given to playback, not editing, during playback. Its a safety/architectural thing to my understanding. I can say that Ive rarely ever seen a PT session randomly dropping fades or edits like other platforms.
Also - the current playback is going through a buffer, so that buffer has to clear and refresh before you hear changes. If you have a smaller playback buffer it will clear faster - I havent struck the sort of delays you are describing though. Id suggest contacting tech support about that one.

3. Ah yes, that old chestnut. Basically TDM is based on a DSP hard driven mix engine and timing/clocking. If you want to bounce, all the math has to be put through those chips in real time to keep the clocking consistent. There's an argument that why couldnt you bounce in even number multiples, but I don't have an answer to that. Either way, its definately a want, but would involve an awful lot of change within the system, which I don't think is likely to happen soon.
Anyways, I hope some of that info is at least partially of use in understanding why you hit what you did. If you're keen to learn more about how to get the most from HD, you may be interested in some of my blog posts:
