Hi!
Just commenting the possible differences between laptops and cellular terminals...
There are different kinds of laptops and also different kinds of cellular hosts. Our
intention is to write this specification as "minimum IPv6 functionality for a cellular
host", i.e. not defining any kind of 'maximum set of functionality'. And this kind of
minimum functionality should be possible to be implemented in even the smallest 2,5G /
3G cellular handsets. An example of dimensions for such a handset could be 11 x 5 x 2
centimeters (1 inch = 2,54 centimeters). Could you compare such a terminal to a laptop
computer? Hardly.
Of course, then there are communicator / PDA type of devices having bigger processor
capacity and memory making it possible to install more demanding applications in them,
but even those devices cannot (in my opinion) be directly compared to laptops.
As a summary, a cellular host (often) has limited size, memory, processor capacity and
battery capacity / power consumption. The users would like to see their terminals to
be usable for quite a long time (typically for some days, at least stand-by time)
without re-charging them.
Cheers,

Actually another thought; what is the difference between a handset and a
laptop that has an embedded 3G radio? Are they both cellular hosts?
