X10 mini bugs (?)

Hi

So far I am afraid I am not too impressed with my new X10 mini pro. Here's some problems and how I solved two of them.

When new the loudspeaker worked for a short while. Then it died completely. I noticed together with the sellers service-department that removing and re-inserting the battery resolved the problem.

Today I tried to connect with my Sony DR-BT50 bluetooth headphones to listen to audiobooks. Making phonecall works, but there is no streaming audio in the headphones, whatever I try, the sound is in the phone loudspeaker (well, at least that works). I try everything, talking to two different people on SE support doesn't help. They say the headphones aren't compatible with their phone. I should talk to sony they say, yeah, right. Funny the headphones works with three other phones.
So, I remember the last problem, removes and re-insert the phone battery.
Guess what. Yepp, now it works fine.

Is this a common problem with this phone, or is it just mine?

I have also noticed that the touchscreen often register a touch when I touch the screen, but the phone does not respond. I have to press two or more times before the phone reacts, even though I can see that the button reflects the first press. This is incredibly annoying when writing, making phonecalls etc.

Is this a common problem with this phone, or is it just mine?

When I press a button on the screen, I need to aim on top of or just above the button to "hit" it correctly. Is there any way to adjust/synchronize this?

Perhaps not the right fora to spew on the X10 mini, but perhaps it will be of help to someone, and to me too ;-)

Thanx
