I might consider the Sager 3790 model, as it has an impressive amount of power for a decent price. In terms of hardware, it does have a few things you need to be aware of. In particular, the sound options are negligable. The integrated Realtek solution is restricted to two channels and is not very good, while the built-in speakers are simply weak. I might try the Creative Audigy 2 ZS Notebook if this is a problem. I'd say the sound is adequate if you use headphones. Headphones help a LOT. This is not really an issue specific to Sager. Most notebook sound solutions are pretty bad.
Other than that, most of my complaints are minor. The integrated web-camera is (not surprisingly) pretty bad and requires a very specific amount of light at just the right angle to be of any use at all. The built-in microphone is weak but adequate.
The trim is gorgeous but accumulates dirt very quickly. I use the Sager very extensively as both desktop solution and a portable multimedia device, and in the three months I've owned the device, the chassis has slight, dark imprints where I usually rest my hands.
All of the ports are on the sides or front, which is both convenient and frustrating at the same time. The keyboard has full-sized spacing, but some keys have been resized - in particular, the function keys, the arrow keys and the navigation keys (Home, PgUp/PgDn, etc).
My Sager shipped with a couple of small issues. The bezel on my DVD-ROM drive was loose and the keyboard was not seated properly, but otherwise everything was fine. The computer arrived with a single dead pixel around 100 x 10, which is pretty negligable.
Sager is pretty anal about warranties and will only honor the warranty as per the contract, no exceptions.
The computer will probably ship with outdated drivers, particularly for the sound. Realtek has been working very hard to improve their integrated sound solutions and has been updating their drivers on an extremely regular basis. If the included video drivers are inadequate, I would replace them with modified ATI Catalyst drivers. Omega drivers have not been released that are compatible with 15.4" widescreen displays.
When all is said and done, however, the Sager 3790 is a great piece of hardware. The 1680x1050 screen is absolutely gorgeous. I personally wouldn't suggest the WXGA or WUXGA options. The ATI Mobility Radeon 9700 w/ 128MB is one of the more powerful portable graphics solutions on the market, eclipsed only by the newer nVidia options, the ATI Mobility 9700 w/ 256MB and the ATI Mobility 9800. The Pentium-M processor is a combination of respectable performance with above-average longevity. The default memory modules were timed at DDR333 and haven't given me any problems, so I haven't replaced them.
The Sager 3790 can be shipped without an OS, which saved me a respectable amount of money, as I already own Windows XP Professional. The case that ships with the computer is okay but not spectacular, as it's kind of thin and doesn't offer a great amount of protection.
The computer clocks at approximately seven pounds with the twelve-cell battery. I do not suggest the six-cell battery.
One final note: although the performance increase on a hard drive is significant from 4200 RPM to 5400 RPM, it is decidedly smaller when moving from 5400 RPM to 7200 RPM.
