Product Review, Bluetooth headset, Sony DR-BT50

Some 6 month ago I purchased a bluetooth headset. Here I would like to write now about my impression of them. There is a lot of talk on the net about the sound quality in bluetooth headsets and how the BT unit is what you pay for, not sound quality. This might be so for true sound freaks, but for me this is not the crucial point. I'm completely happy with the sound quality and I'm quite sure there are other factors that affect this more (pod, sound format, surrounding environment etc...). So my list of pros and cons:

Pros

• Very comfortable
  
• Excellent sound
  
• Great battery time
  

Cons

• Too short buffering time of the music. If the headphones looses connection there is a glitch in the music.
  
• The microphone is way to sensitive. It is not possible to use the headphones for talking anywhere but in the home with no other sound playing. In particular on the bus or in the car you can simply forget about using them. The person you'r speaking to will go mad.
  
• The two hoops holding the two speaker units (one for each ear) should have been made in aluminium as parts of the main hoop is. I managed to break on of these fairy fast. Now I reinforced them with my own aluminium hoops, but of course it would have been nicer not to have to do that.
  

Free will

I had an interesting discussion with a friend of mine the other day. The question we started to discuss was weather free will exists or not. Of course, this question has bother me, as probably most anyone, before. But I think we managed to get to some interesting conclusions this time.

First it is important to try to classify free will. Free will is not a deterministic process. It means that a system possessing free will is not possible to describe with mathematics, so it is not possible to tell how the system will respond to a given input.

Next it is important to note that free will is not a random process, as suggested by some. Free will is neither of these two. Therefore it is so hard to classify, because we only know about these two types of processes.

So, out conclusion now. Free will is a process where it can not be determined how it will respond to a given input by any external derivation (as for deterministic processes) or external statistics (as for random processes). But it can be foreseen (or determined) by the process it self! So the system possessing free will can it self determine how it will respond to a given input, while still no other process can make that deduction.

Now this ides I think is in no way new. I believe this is what Douglas R. Hofstadter tries to claim in Gödel, Escher, Bach. I would like to make a prediction, or definition or what ever it should be called, with a more formal claim about a system possessing free will: A system possessing free will is a system that can (however that is done) solve the halting problem for it self.
