Thanks Frank,
I had a look at thinkwiki but couldn't find what I'm looking for.
I also thought about netbooks but they won't cut it in the long run and
I'll need a laptop eventually anyway.
Could you post a lspci of your new acer as well? It's not quite what I'm
looking for but it might be helpful anyway.
Thanks,
Philipp
It feels like my several year old PC will crap
out soon for one
reason or another, so I need a replacement, better sooner than
later. This time it should be a laptop and I heard that formerly
IBM and now Lenovo thinkpads are of good build quality, even if
they only come with intel CPUs and cost an arm and a leg.
The Thinkpads seem to have a pretty active net community doing sites
like www.thinkwiki.org, which are very helpful. There's nothing bad
about Intel CPUs, actually I consider them the best choice ATM for
laptops, especially if you get a device with an Intel gfx chip
inside, they have excellent FLOSS drivers. Personally I agree that
Thinkpads are a bit overpriced, you can get equivalent laptops
cheaper from manufacturers like Acer or MSI, which are the two
companies I have first hand experience with: I have an MSI S260 which
currently gets replaced by an Acer Timeline 3810T. Both are well
supported by Linux. The new one requires bleeding edge software, i.e.
Debian unstable in my case. On the ACER, no interrupts are shared
when AHCI is enabled, but I guess, that's normal for AHCI:

I didn't yet do any hardcore audio tests on that laptop, it's running
an upstream large latency kernel. With laptops, I think, it's
important to know your ways of using it. For example, the Acer is not
the fastest device around (it's just a single Core CPU), but it's
very light (1.65kg) and has an amazing battery life (up to 8h with
dimmed display), so it's great to take on the road which is where I
will be using it the most and where I can deal with a slower CPU, but
not with a huge and heavy monster. The other extreme would be a
netbook, but I prefer the 13" screen of the Acer - my eyes don't cope
well with 10" screens, and Atoms just don't cut it in the long run
for audio work. So to me, the Timeline is a good compromise, but your
compromise will probably look different.
