Since I don't use TI, I'm at a disadvantage in deciphering all this.  It may
simply be a matter of terminology and mixing them up (could be you or me doing
that - I'd bet on me).  A clone, to me, means copying a working disk directly
onto another of random size (as long as everything fits).  If that's the proper
usage, it's not a bit-by-bit copy - twiddles are incorporated to adjust for
different partition sizes, etc.  Are the sizes you show above actual partition
sizes, that is, you could plop the USB drive into the system and have it work? 
It looks like this is the case.

The bit-by-bit copying usually involves copying something that the software
otherwise doesn't know how to handle.  Older versions of TI wouldn't know how
to handle Linux partitions so they would copy them verbatim, as it were, rather
than parsing the file system and copying only used sectors.  Compression would
make them smaller but not as small as could be since the unused sectors may
well contain random data which doesn't compress well (in these cases it's
suggested to use a utility inside an OS that can read the partition and fill
all unused space with zeros so compression works well).  You can clone this but
you can't change the size since it's not know how to do so - you get a
bit-by-bit copy.  The other partitions can be resized since it's known how to
compensate for extra or less space on the destination.

It's unknown without using the software interface to browse through the files
embedded in those files.  That's the normal/proper way to handle backups since
the data is all concatenated and compressed together (think ZIP file).  You
would extract individual files/folders in the same way you would from a ZIP
file, only using the TI interface.  BTW, you can create one huge file rather
than 45 separate ones by selecting to not break them into chunks suitable to
writing onto, say, DVD.  If you're not putting them on external media, there's
no advantage in breaking the backup into chunks of any size (other than those
dictated by the file system - 2GB for FAT).

I installed the beta at one time and wasn't overly impressed (it was beta
software, of course).  I wouldn't go out and buy it just to have it since it
doesn't offer any advantage compared to what I have now.  New hardware will
likely come with it installed and I'd be fine leaving it on as long as there
were no problems with it.  My son bought a refurbished Dell laptop and had
nothing but BSOD with it, even after reinstalling, adding drivers and updates,
etc.  He eventually got XP on it (after downloading the XP drivers first, of
course) and it's been rock-solid.  That's a sample of one but may indicate that
the system wasn't fully Vista-ready, even with the latest BIOS update.  That's
something I'll ponder as we near getting a new laptop for my wife. We're
looking at alternatives such as the Eee but we'd like to have a hands-on
experience before making the plunge and they simply aren't available locally
here.

So many options so little money...  ;)
