Thinkpad X60 — the Tablet Goes Ultraportable
Rovi writes "Lenovo had a gift for Thinkpad fans this season- they finally released the successor to the X41 Tablet. The Thinkpad X60 Tablet weighs in at about three and a half pounds and has great tablet functionality. The updates from the older model include a 2.5" hard drive (the X41 used a 1.8"), automatic screen orientation, and an Intel Core Duo processor. For performance seekers some serious upgrades are available, such as a 120GB 5400RPM hard drive, 100GB 7200RPM drive, SXGA+ monitor, or up to 4GB of RAM."
My understanding is that they should perform identically. The low voltage one was just able to pass the test at that voltage where the "normal" one would have failed the test at that low voltage. They make them all the same, then bin them based on which tests they pass. The exception to this is if they have high demand for 1.6 GHz chips but are producing lots of extra 1.8 GHz chips they may re-mark them and sell them as 1.6 chips (which is why sometimes the slow speed grades overclock so well).
This is my understanding. It's a bit like military spec chips. They perform identically, they are just designed for different conditions (in this case, less voltage).
Comment forecast: Bits of genius surrounded by a sea of mediocrity.
Yes the X-series tablet will run linux distro's to your hearts content, however like I said many of the features will be unavailable, including any of the ThinkVantage Technologies that Lenovo puts on them such as the RapidRestore, or Access Connections programs. http://www.thinkwiki.org/
Towards the end, IBM's choice of laptop hardware and their BIOS ACPI tables worked very well with Linux. IBM's support may translate some, since Lenovo started from a good position and were not necessarily inclined to deviate for no reason (Also, Lenovo bought the employees too, so the tendency would be strong). My biggest concern is if they continued to take care to do the ACPI tables properly or not going forward, but having the same firmware developers gives me hope.
XML is like violence. If it doesn't solve the problem, use more.
