Samsung Q-series laptops and Linux

Dear lazyweb: I've been a satisfied IBM Thinkpad X40 user for about three years, and the fact that the X40 is still one of the most commonly seen laptops at geek conferences speaks for the machine. However, as my baby's end-of-warranty approaches, I am toying with the thought of a new laptop, with which I'd also like to address some of the issues I have with the X40, namely that it supports at most 1024x768 pixels on the screen, is limited to 1.8" harddrives (which to my knowledge come in 40Gb and 60Gb variants only and are quite slow), and whose Pentium M 1.4GHz processor often reaches its limits, even though I rarely do very computationally-intensive stuff. On the other hand, I get a good 4 hours of battery run-time out of the machine.

The Lenovo Thinkpad X61 would be a logical successor, but it has not won me over: it looks and feels a bit clunkier, has under 3 hours of battery time, and the screen is still limited to 1024x768 pixels. There's the Lenovo Thinkpad X300, which comes with a 64Gb solid-state disk which will weigh even less on the battery, but the the machine is still too expensive, it's first generation (meaning it'll have more problems than a second generation issue), and the options for extending the storage capacity seem limited.

While visiting Penny in London, we passed by a number of electronics stores, and the Samsung Q45 and Q70 models attracted our attention. We would love to hear any feedback from owners out there (and maybe you could send us the output of lspci -vv, lsusb -vv and the file /var/log/dmesg, please?). After Lenovo has switched the Thinkpad power adapter plug format, I have very little reason not to look elsewhere…

The "ultra-mobile" Q45 (which would be a Thinkpad X-series competitor) comes with an Intel Core Solo, Duo, or Duo 2 processor, clocked at 1.6GHz, an Intel graphics card and the 3945BG wireless chipset (or its 4xxx successor), uses a 2.5" harddrive, and its 12.1" screen can display a resolution of 1280x800 pixels. It weight just under 2kg. We've seen models with 3Gb of RAM and a 320Gb harddrive for a little over 1000€.

The "business class" Q70 (a Thinkpad T-series competitor) has an Intel Core 2 Duo processor clocked between 1.8GHz and 2.4GHz, and its 13.1" display can also display 1280x800 pixels. It seems like it will require a bit of effort to find one with an Intel graphics card, though — I am not going to get a laptop with anything else, mainly because of Intel's excellent dedication to open source. The devices are over 2kg in weight, and a 3Gb RAM, 320Gb harddrive version costs about 1400€.

Does anyone have experience with these laptops and could speak for or against them? Also, what other laptops (not desktop replacements or lap warmers) might be worth looking at? You can leave a comment, or write to me. Thanks!
