Well, if one has a limited range of laptops (eeePC and different versions of
MSI winds: they almost have the same HW), one can choose USB sticks which
manage to boot, even in very little french province towns...
For power greediness of USB sticks : even 16G can be put on any plug of MSI
winds.
For power needs of external USB CD drives: the only brand I found had only one
plug (some cleverly designed external disks have a plug for USB and a plug for
5v, if needed), thus making it very dependant on the quality of its wire (one
has to choose a evry short one). It somehow works, but it is very unpleasant
(and Y shaped USB wires, with a plug for +5v and onother for a full USB always
lead to confusions).
Such configurations, when used with a "net""book", need external power supplies
("net""books" were meant? -sold, anyways- to be independant.)
As live CDs remain slow, an use USB sticks for the same function (eats less
mAmps, is faster), once I find a brand which suits my computers (and my
nephew's ones).
I noticed that external disks (real, rotating ones) could be used to boot, and
were little power demanding : I tried with real installations of Mandriva,
Fedora (14 to 16) and Mageia and read Debian could , too: the advantage I saw
was one can use the package manager (installing software on a RO support such
as a live CD or its image is difficult). This real installation could be
achieved with sticks, but was very slow (USB sticks have long writing times
-but short reading ones {a 1/5 ratio or worse} ; mechanical disks are fast
enough, on reading and writing). The mAmps demands remained modest, as I could
carry my computer to a restaurant and use it.
This is cheaper per Go than USB sticks (an 1/20 ratio) and seems, with new
disks, very comfortable.
There is another issue with CD's /DVDs : it is becoming harder and harder to
find such things, but rotating disks and USB sticks seem easy to find, even in
small towns....
Have nice days...

Our local Linux Users Group (oclug.on.ca) has been finding unfortunately that
the issue
becomes one of which USB sticks will boot in which laptops. So far we keep
finding some
combinations work fine, but others don't. That is, stick 1 that boots fine on A
B and C
laptops won't boot on D and E, while stick 2 boots on A B and D but not C and E
etc. This
has stopped us doing Linux promotions by offering a live-USB because we found
too many
cases where novice users can't get their machine to boot.
I've had good success with several different USB CD/DVD reader/burners as long
as I make
sure they are properly powered (there is usually a separate power input),
especially on
burning. Some USB ports e.g., the LH one on some Asus Eee and UL30, don't seem
to be fully
powered, so I tend to use a 5V "brick" or a nice little Belkin power bar that
has a couple
of USB power slots meant for charging cell phones.
I'm probably getting into off-list territory here, but I've been finding in the
last while
that a lot of "failures" or "unreliability" alleged in technical lists turn out
to be
silly things like devices not getting power when apparently plugged in.
