Seem some of these things are hit an miss.
The restart thing is the OS and/or the drives boot sector that can often be remedied with a clean install or going back to the original factory image and starting fresh. A lot of times conflicting drivers cause the lagging start with the black screen. Sometimes if you just wait and walk away and come back later it will have started and fixed itself. Forced restarts on go to further aggravate the situation and add on the OS having to recover from something it was struggling with in the first place.
Audio has been hit or miss. Some report issues with the sound card making a popping noise when coming out of standby while others like me have had zero issues on 3 machines.
The Bluetooth problems you are describing can almost always be attributed to RF interference. A single 2.4 GHZ wifi channel that is 22MHz wide can cross over with 1/4 of the 79 blue tooth channels that are 1MHz wide. BT uses frequency hopping so when it experiences interference it hops to another channel. Some times its quick to find a clean channel, sometimes it takes a little while. Makes for a PITA, I know but thats the RF overloaded world we live in today. If you live in your own house you can at least control it by going to all 5GHz Wifi and shutting down the 2.4GHz. If you live in an apartment building or anywhere else where you have neighbors in close proximity you are screwed. Even cell phones and land line wireless phones can come into play. While having BT built in and the ability to connect to multiple devices using the same TX/RX is great it poses its own challanges. Often its better to use devices that are frequency and code dependent, like Logitech wireless mouse that is not BT but uses its own USB micro RX. Mouse wont connect to anything else, nothing else can connect through that receiver so the only time you see it drop out is when you forget to charge the mouse!
