I read: I think this an urban myth, the Nvidia drivers may be proprietary but they are well functioning. I think this is a pretty rural comment, there is more than x86, where are the nvidia binaries for 2.6, and personally I really don't feel like loading a binary only module. regards, x -- [EMAIL PROTECTED] Postmodernism is german romanticism with better http://pilot.fm/special effects.

Or is this extra quality just a myth ? I'm probably getting a powerbook for my next machine - they are well built (a lot of people run them at work), the screens are not particularly high res, but they make up for than in weight. The newer ones require kernel 2.6 AFAICT to get the video running properly, but that shouldn't be a huge problem. I haven't check up to see if suspend is working properly - thats a crucial isue for me. I guess the more of us who buy them the quicker the endianness problems will be fixed, ppc-linux-audio-user? :) - Steve

They are simply great, quiet, cool, powerful (at least the G4 one) machines :-) The new AlBooks DO have mic-in and line-in again! Stay away from nvidia on any non-x86 platform, you will never get a decent driver for those graphics-boards, whereas ATI-drivers at least offer good 2D-performance on newer chips and eventually will offer full OpenGL-support. (read: ATI is more helpful than nvidia, though their support of the dri-project lags a bit behind their x86-binary-only-drivers) Have fun* Niklas

Best regards Christian I use Dell Inspiron 8200 with NVidia's Geforce4Go (64MB) and in the last 2 1/2 years only had once a problem like that with one particular release of the drivers. Simple downgrade (and later upgrade to the fixed drivers which were released promptly resolved that without a hitch). In addition, Nvidia's drivers, although proprietary, have a nifty installer that automatically detects the platform and install proper version of the driver (and/or recompile the non-proprietary aspects). I heard somewhere that some of the Linux distributions now ship with these drivers included. As far as the noise is concerned, Centrino notebooks are now the best for noise-free high-performance settings. 1.7GHz Centrino notebooks beat the living daylights outta 2.4GHz P4 desktop in performance, mainly because they are a complementary mix of P3 performance and P4 scalability. They also offer great battery life (sometimes even upwards of 5+ hours per battery). My notebook is 1.8GHz P4 and it rarely kicks in a fan when working with it. It usually does so when playing highly demanding 3D games. Dell laptops also have nifty but Dell-unsupported Linux tools that enable you to control the CPU and Fan throttling hence enabling you to completely shut them off (obviously if you fry your laptop in the process that is your own problem). I've used this feature without any problems so far and the P4 downclocked to 1.2GHz is still plenty fast (although lately I've been topping off the cpu with my real-time stuff, something that really annoys me :-). To give you a perspective on this matter, on the last conference I had the laptop on-stage with 2 batteries in it charging (hence extra heat was being generated) set between two pianos. Since my piece was not first on the program, some bright soul decided to cover both pianos with the thick protective piano cloth. When I realized this in the middle of the concert I almost screamed thinking that my laptop would end up in a pile of smoldering goop, especially considering the fact that the darn thing was turned on with the power management disabled (I wanted to make sure that the screensaver or some stupid thing did not impair my performance) and on top of that charging the batteries. I was very pleasantly surprised when my number finally came to uncover the cloth from the pianos and the laptop and realize that my laptop was completely cool, if barely warm to the touch. Fans never kicked in. I like Dell for one more reason, their support/warranty is awesome. Sure, here or there you stumble across a pretty mentally challenged tech support person that asks you stupid questions and guides you through the steps that defy common reasoning, but most of the time they are very prompt (whenever I had to get my laptop fixed, the tech person would come to *my home* the very next day with the necessary parts, even if that had to be the whole motherboard and fixed it within minutes -- Disclaimer: I live in US, not sure how it works in other countries) and helpful. On top of that, when everything fails (i.e. they have no idea why laptop does what it does), they provide you with a whole new system! I initially bought a refurbished Inspiron 8000 P3 800Mhz with an old Ati Rage 4 Mobility (32MB) (their refurbs get a great price/value ratio and the same support as the new models) and throughout the years when it broke to the point they had no idea what was wrong, they replaced it with the current Inspiron8200 1.8GHz P4 at no cost to me. I also was able to upgrade the video card by myself (from geforce2go to geforce4go -- Dell has the spare parts division where you can get this kind of stuff) without a hitch, although this may void your warranty if you screw something up. Anyhow, Dell really worked well for me. Some other people were perhaps not as lucky as me and may have had pretty rotten experiences
