Recently I measured the CPU load and battery run time of some low-delay
audio DSP on an Asus Eee PC 701 (Intel Celeron M, 630 MHz), and on an
Acer Aspire one (Intel Atom 1.6 GHz). The time spent in the CPU was
pretty much the same for both systems, and the battery runtime was
between 3 and 3 1/2 hours on the Asus (Celeron) and 2 1/2 hours on the
Acer (Atom). Here is the data:
algo1
Asus: 56.4% CPU, 3h14' battery
Acer: 51.0% CPU, 2h28' battery
P4: 20.5% CPU
algo2
Asus: 49.8% CPU, 3h16' battery
Acer: 47.5% CPU, 2h09' battery
P4: 16.5% CPU
algo3
Asus: 36.5% CPU, 3h22' battery
Acer: 35.0% CPU, 2h27' battery
P4: 13.0% CPU
jackd
Asus: 6.0% CPU
Acer: 4.8% CPU
P4: 2.2% CPU
Sound card IRQ handler
Asus: 4.5% CPU
Acer: 4.2% CPU
P4: 1.0% CPU (network interface with netjack)
P4 is Intel Pentium 4 @ 3 GHz. I know this is no perfect benchmarking,
but gives an idea of the processor performance.

Apparently there's this new thing called an
IndiaMixx which is pretty much my Asus EEE pre-configured with a Linux Audio distro,
Ardour, and EnergyXT (whatever that is).

Very under powered ->> 1.6Ghz Intel Atom CPU
If it's like the other netbooks, the keyboard is a bit smaller too
with a 9" or 10" screen.
Definitely cute and useful in certain situations. IMHO, this computer
is good for taking (text) notes in class. You could also get the same
machine for $375 (someplaces $345) and install your own distro and
audio apps. I helped a friend install Ubuntu on an AspireOne - which
is how I learned about it's performance (and lots of scrolling around
to read.)
