I found this FAQ list and have taken only a small part of it but the things that most people wont know and some things that make you go wow thats great and ouch I better be careful here cause it might not work.

Q. (Networking) Are there any problems with mixing PCs that run older versions of Windows with ones that run Vista?
A. Unfortunately, yes. Windows Vista uses a new protocol, Link Layer
Topology Discovery (LLTD), for networking. LLTD speeds up the process
of connecting to other devices, and it allows Vista to grab information
about each device and display it in the Network Map. But earlier
versions of Windows lack LLTD, so PCs running older versions of Windows
may not show up on the Network Map at all, or they may appear
sporadically, or they may show up only after a long delay. Microsoft
says that it intends to release a patch for XP that should solve the
problem; but as yet it has no similar plans for earlier versions of the
OS.
Q. What about product activation–any changes from the version that XP uses?
A. Microsoft’s product activation–software that profiles your
system’s hardware and uploads a fingerprint-like profile to a database
maintained by the company–is alive and well, and in Vista it isn’t
optional. Microsoft can change the stringency of its product activation
system, but rest assured that the company will be checking to make sure
that you don’t install your copy of Windows Vista on more than one PC
at a time…. So if you have 2 home PC’s get ready to be poor and have to buy 2 copies of Vista!
Q. If Explorer’s Search is so great, why couldn’t it find the Word file I created yesterday afternoon?
A. You’ve discovered one of Search’s dirty little secrets: By
default, it restricts its searches to a limited set of folders on your
hard disk. Search uses an index to speed up its searches; but Vista
indexes only a few folders, such as your own personal user folder. If
you create folders outside that area, the OS won’t index them, and
Search won’t find them or their contents. There is a workaround: If you
do an Advanced Search (select Start, Search, and click the Advanced
Search down arrow), you can instruct the tool to look in nonindexed
areas; just check the box next to Include non-indexed, hidden and
system files (might be slow). This unfortunatley is not a patch on the current OS X Tiger spotlight search which does every file on your system in the blink of an eye and this will be improved again in the upcoming “Leopard OS X out early next year
Q. Do I have to buy a different disc for the 64-bit version? (or any other version)
A. Each retail version of Windows Vista will contain 32- and 64-bit forms of the OS.
I have heard this means all version of Vista are on the one DVD they just arnt unlocked unless you have the right key and use the new very stringent validation process.
Q. If I get one version, can I upgrade to a different one later?
A. Yes. Microsoft plans to add a Control Panel applet that will let
you upgrade to a more feature-rich edition of Windows Vista, presumably
by using a credit card. Pricing and other details have not been
determined (or revealed to the public) as yet.
Q. Can I run Windows Vista on a Mac?
Yep. The two major options for running Windows on a Macintosh system–Parallels and Apple’s Boot Camp–both support it.
Q. Can I make Vista look like an older version of Windows?
A. Yes indeed. Right-click the Start button, select Properties, and
choose Classic Start Menu to get a Start menu that’s composed primarily
of cascading menus that lead to programs. Right-click the desktop,
select Personalize, and double-click Theme to choose the Windows
Classic theme, which does away with much of Vista’s slickness (and
gives you a Start button labeled “Start”). Take both of these steps,
and Vista will have a decidedly old-school, Windows 2000-like flavor.
What Vista doesn’t seem to have is a way to make its Start menu
behavior and other aspects of the OS behave more the way they do in
Windows XP.
Q. I heard that Windows Vista itself will sometimes decide to disable Aero. What’s up with that?
A. In general, Vista will disable Aero if it determines that it
needs to improve performance, recover from a technical issue, or (in
the case of laptops in power-saving mode) reduce demands on your
battery. According to Microsoft, Java apps are the most common trigger
for disabling Aero. Remotely viewing or sharing another machine’s
desktop can cause Vista to disable Aero, too, and Vista disables Aero
when presenting a User Account Control (UAC) elevation prompt.
Q. What’s this 3D task-switching thing?
A. Now you’re talking about some serious eye candy. Windows Flip 3D
(Windows-Tab) is Windows Flip with a membership in the Flying Walendas.
It stacks your windows in three dimensions, and lets you scroll through
them with your mouse or click one to select it. It adds up to sort of a
poor man’s Expose (from Mac OS X Tiger).
Q. Will my existing antivirus software work on Windows Vista?
A. Probably not. Vista is different enough from previous versions of
Windows that antivirus software written for older versions of the OS
won’t work on it. You’ll need a version written or rewritten
specifically for Vista. Symantec and other makers of major antivirus
software have announced Vista versions of their programs.
Q. IE 7 is it OK?
A. IE 7 is a major step up from its predecessor, but Firefox
is safer, has more features, and is far more customizable with add-ons
and themes. IE 7 remains a valuable option when you encounter one of
those clueless, IE-only Web sites. (Note that IE Tab or IE View will
still let you launch IE from within Firefox.)
Q. What’s this I hear about thumb drives speeding performance?
A. Instead of shelling out for extra RAM, you may be able to give
your Vista machine a bit of a boost by using a USB thumb drive. A
Windows feature called ReadyBoost lets your PC use free memory on a USB
flash drive to augment RAM. You’ll need, at a minimum, a drive that has
256MB of free space and can read data at 2.5 megabits per second and
write data at 1.5 mbps; to qualify for a Windows Vista logo, the drive
must have 500MB of space and read/write speeds of 5 mbps/3 mbps.
You’ll soon start to see flash memory boosting speed in other ways,
too, thanks to the ReadyBoost and ReadyDrive technologies built into
Vista.
Q. What do ReadyBoost, ReadyDrive, and SuperFetch do?
A. SuperFetch, a new memory manager for Windows, uses available
memory to proactively cache data that you’re likely to need.
Eventually, it learns which applications and data you (and any other
users who log in to your machine) habitually use and when you use them,
and it does so on a per-user basis.
ReadyBoost makes more memory available to SuperFetch by creating new
memory pages on USB flash drives and using the flash memory in hybrid
hard disks.
ReadyDrive uses the Non-Volatile RAM cache on a hybrid drive to
store critical data during state transitions such as when booting your
PC or resuming from standby. Before shutting down, Vista transfers the
critical data your PC will use for booting or resuming into that NVRAM
cache. As a result, the PC doesn’t have to wait for a hard disk to spin
up before it can start loading data.
Q. Because of Digital Rights Management for
prerecorded high-definition media, will I need to buy a new monitor to
play premium high-def content?
A. You might, regardless of whether you’re running Vista or Windows
XP. For a PC to send next-generation video content to a display, the
display must support HDCP–and while most HDTVs do support this
copy-protection technology, many older monitors that support high-def
resolutions do not.
Heres the original list be warned it is HUGE !
