I tried piping dd through pv (pipe viewer) and the speed was very 
variable. It shows speed and data transferred. Sometimes many MB/s, 
sometimes just a few kB/s (on ubuntu). No idea why. Oh, the system 
performance graph applet show lot of (full graph, so almost 100%) IOWait 
activity, maybe it helps.
of course I did it with bs=1M
I'm not an expert but I thought that writing 1M block should be pretty 
fast (my stick writes around 9MB/s), when I write image using win32 
imager, it's fast all the time.
since dd works in a low level (not sure how low though ;) ) and not in 
filesystem level I thought it will comparably fast. It's well known that 
copying many small files to flash drives is slow, so working in low 
level should avoid it. But no, it's slow anyway.
It would be nice to figure out some setup which would help the speed up.

The booting time was just a general complain to see if it's just my 
laptop or if others have the same too. Although it's not perfect, I 
think it's one time activity, so it does not bother the average user, 
who install the system just once in a while.
