Sorry... It was not my intention, I try to avoid ranting, but can't help it
I like to do optimization, I usually do compiler optimization tests and
benchmarking on some stuff at work, although I'm also interested in doing
code optimization if needed.
The XO has several areas I'd like to see improved but I think I'll start by
this one. I've seen a bit of ongoing effort on the wiki, I'm thinking of
talking to the people involved when I get some results from my Gentoo tests.
I also saw the "Browse needs tabs" ticket and I thought I might try a shot
at that also.

Definitely. Anything particular in mind?

I thought of submitting a bug that said "XO needs SWAP badly" or something
like that, which I abstained of doing until I could understand the
motivation behind not using swap at all in the XO, when a 2GB SD card costs
3eur at retail here - seems a good compromise given what is achieved from
the small extra cost. My XO was constantly "crashing", now it's just a bit
slow moving from app to app.
>From what I read since I subscribed the ML, it seems to relate to battery
life dropping with SD cards but that's the only thing that I've read until
now. Having the XO constantly crashing will probably kill the battery life
more than having the SD card there.
This review by a 12-year old (
special attention to the fourth paragraph, if it was a 12 year old who
wrote that) pretty much sums all the biggest problems I see in the machine,
as does the praise for what's awesome with it.

Hmm.... ok. Is it possible/easy to use the whole touchpad as pointing
device, instead of just the middle. Since the middle has no "bump" that
could give some feeling of where it ends, enabling all would make it more
usable. At least I, frequently, need to look at it to understand if it's
going bonkers on me, or if I'm just trying to use it out of the it's limit.
I don't see a practical use for all that wideness but it would just to be
less error prone.

Not really, I just hacked a driver once to add AGP and IDE DMA support for a
VIA chipset, just added the hardware IDs.

More than what I'm doing already, I can't. Even more when the government
here is financing Atom based Classmates with both Windows and Linux for
50eur. I can't lie and say it's a more capable device for us, although in a
third world country it is.
Just wish they would've put Sugar in the Linux distro, it's just a KDE basic
stuff. At least, Kids seem to like Supertux - not all is lost for M$.

That's my view on it, although I don't have any experience in Python
programming. Launch time doesn't really bother me, memory consumption on a
device with no swap and 256MB of RAM does. Is it just Sugar/Fedora/XO distro
Please elaborate on what you mean by 8.2 taking much longer to launch. That
would be something I would be interested in looking at, although I don't
think I have what it takes to "fix" Pyhton itself, if that's what's needed.
