IBM also jumps on the bandwagon with T61 and R61!
http://gizmodo.com/gadgets/hands-on/lenovo-t61-thinkpads-magnesium-rollcage--wolverines-bones-258878.php"It has come to my attention that the T and the R series Thinkpads, which were leaked by specs last month, have gnarly magnesium roll cages that remind me of Wolverine's reinforced adamantium skeleton. I've always been a Thinkpad fanboy. And while most of the other PC makers are handling this Santa Rosa launch with minor upgrades, I'm so glad to see the Lenovo Thinkpads are still evolving with robust engineering. These are the fastest, toughest, quietest Thinkpads ever."
There's a 3D, honeycomb sub frame below the surface, which makes the lid not only stronger, but roughly 50% more durable against uneven impacts (like a baseball hitting the back of the LCD in one point). The antenna for WiFi and WWAN is placed inside the plastic, but outside the lid cage, so reception is 2x that of the previous generation. Flexing the laptop hard resulted in minimal flex, and only a bit of protest from the optical bay. I'm tempted to make comparisons to toughbooks and other rugged notes, but I'm unqualified to do so.
Oh, I'm also happy to report that the IBM moniker, while not on the wrist rest, isn't gone as reported. The logo, which is available for Lenovo's use for five years from the purchase, is still on the lid.
The Thinkpads also have better thermal management, thanks to extremely tweakable software that shows you how much additional juice you get from turning components off, as well as better cooling hardware, along with that rollcage doing a great job of dissipating heat. And they've even gone and made the bottom a little bit more Mac-ish than the fugly old bottoms. It still has the drive head parking, which it pioneered before the Macs, and a fingerprint reader which is my preferred method of signing into Vista these days.
And they've got some 1GB of memory hanging off one of the express card controller (you'll have to sacrifice something) to be used as a disk cache. This is their alternative to using hybrid drives. They found it to be much faster than the very limited 256MB on a drive, and now you can swap in big old perpendicular drives without losing your big cache. It's called Intel Turbo Memory, and they find that it can bring a 5400RPM drive to faster then a 7200RPM drive in some cases."
