Only heard of a couple of cases, and a visit to a Nokia Care Point and having the handset re-flashed solved it ! You can check for any software updates and try a hard reset first if you like as everything will be erased with the re-flash anyway ? Check for updates on phone or Ovi Suite, then dial *#7370# followed by 12345 if asked, but back up your contacts, calendar and notes ONLY first.
Good Luck , hope you get the phone working ok, it's a great piece of kit, I love mine 
As you've already found out, you can't remove the battery on the E7 unless a NCP does it for you. What you can do is to turn it off by pressing the powerbutton for about 8 seconds untill you feel 3 quick buzzes. Then you can release the powerbutton and press it once more to turn it on (as normal - one buzz only). As Nokia has said, this is pretty much the same to the E7 as pulling out the battery of another phone.
The hard reset button wise isn't recommended as it wipes the phone for ovi store which I don't know yet if can be installed again without going to a Nokia care point. From a few other posts regarding the N8 it seemed like it was fixed with that phone, but I can't tell you if it's fixed for the E7 yet. Maybe someone else can? You are better off doing the soft reset as carman has already mentioned in his post above.
I had to do it as my E7 refused to turn on and got the reflash of fw to get ovi store back done for free as it wasn't my fault that it wouldn't turn on. So if the case is like that it should be pretty safe to do it. But the ovi store issue might have been fixed also for what I know. I remember I read that with the N8, after doing a hard reset, you did a soft reset and then installed the ovi store client from sw updates but use the search bar and check it out or call a Nokia care point to get more information before taking any actions.
I really suggest you do that!
The soft reset hasn't bricked my E7 and the hard reset made mine come back to life which tells me that it was something else that was the problem with my E7. This has only happened once though. Since then my device has worked pretty good, bazyeo. Whatever dude, good luck with your crusade against Nokia Australia...

So my phone is back with the local Nokia Care Centre for reflashing again. I also believe Nokia Australia are going to call me again next week to check to see if I am happy.
One other interesting point. In the email I received last monday Nokia addmitted to me that the two E7 phones that I have had were part of an initial batch which were received by Nokia Australia and as such were used by Nokia staff for testing and evaluation purposes. If that is true (and that is what the email says) then I do not believe that those phones should have been released to the retail sector to be sold as new phones.
I have checked with Nokia Australia regarding the issue of the prior use of these devices, and what they explained was that they were part of a batch which was routinely quality-checked, they were not used for evaluation of the model generally as you appear to suggest. Routine quality checks are performed under factory conditions and involve a Quality Assurance Operator checking the functionality of the handset using predefined and stringent criteria. Nokia Australia has also provided information that due to a failure in the process, the access points established for this purpose were not cleared after the check, an issue that has since been dealt with by improvements to the QC processes undertaken.
