So when do we see Vista ReadyState ... the OS locked onto a USB Thumb Drive,
eventually built into the OEM MB? Gonna happen?
Do you mean ReadyBoost? I've not heard of Vista ReadyState.
If you do mean ReadyBoost, it doesn't make sense for OEM's to build this
into the MB as a more effective solution from a manufacturer and
end-user standpoint is to add more RAM. ReadyBoost can help if you need
a quick, but smaller boost in performance but don't have the ability or
time to add extra RAM.
ReadyBoost caches the pagefile in flash memory so that it doesn't have
to hit the HD when it needs virtual memory. But a better solution to
speeding up VM access is to eliminate the need for VM usage by adding
more physical memory.
If, instead of ReadyBoost, you were referring to BitLocker, then what is
required is a motherboard that supports TPM version 1.2. Many OEM's
already include this on their PC's. For examples:
"Which Dell systems support TPM?
The TPM 1.2 security hardware device comes standard on the following
LatitudeTM notebook systems: Latitude D420, D620, D820, OptiPlexTM
desktop systems: Optiplex 745, 740 and Dell PrecisionTM Mobile
Workstations M65, M90. Dell recommends the use of Microsoft® Windows®
XP Professional XP Professional operating system with TPM which includes
advanced security, mobility and networking features. TPM is currently
not supported by Dell on Red Hat® Linux® operating systems. Customers
who deploy TPM should also purchase Wave Systems Embassy Trust Suite
from Dell Software & Peripherals to enable full TPM features including
key archival and migration. "

If you are looking to purchase new, ask the following questions when
requesting a BIOS:
1. Does the computer have a Windows Vista-ready BIOS? Does it pass
Windows Vista logo tests?
2. Is the BIOS Trusted Computing Group (TCG)-compliant?
3. Does the BIOS have a secure update mechanism to help prevent a rogue
(malicious) BIOS from being installed on the computer?
But, you don't necessarily need TPM 1.2 to use BitLocker with a USB
drive. From the FAQ:
"Can I use BitLocker on a computer without a TPM version 1.2?
Yes, you can enable BitLocker on a computer without a TPM version 1.2,
provided that the BIOS has the ability to read from a USB flash drive in
the boot environment. This is because BitLocker will not unlock the
protected volume until BitLocker’s own volume master key is first
released by either the computer’s TPM or by a USB flash drive containing
the BitLocker startup key for that computer. However, computers without
TPMs will not be able to take advantage of the system integrity
verification that BitLocker can also provide.
To help determine whether a computer can read from a USB device during
the boot process, use the BitLocker System Check as part of the
BitLocker setup process. This system check performs tests to confirm
that the computer can properly read from the USB devices at the
appropriate time and that the computer meets other BitLocker requirements.
To enable BitLocker on a computer without a TPM, use Group Policy to
enable the advanced BitLocker user interface. With the advanced options
enabled, the non-TPM settings appear in the BitLocker setup wizard."
