Hello,
There are many features that Vista exposes at a technical level that make a
compelling case for upgrade, depending on the person's needs.
Just a few technical examples:
Updated networking: Much more efficient network stack, especially when
coupled with other Vista (and eventually Longhorn Server) machines. Compared
to XP, uses your available bandwith much better (maintains throughput),
especially in high latency scenarios (i.e. satellite linkage).
New way of putting pixels on the screen: It may seem like just eyecandy, but
this will enhance the performance of current multimedia apps and feed the
next generation of multimedia applications, both games and more traditional
apps. Features that are unavailable in XP, such as the desktop composition
engine, and specifically allowing video memory to be virtualized/swapped and
forcing the video driver to properly implement scheduling, really unleash
the power (and ability to multitask) these apps.
Advanced printing and display: Vista supports high-DPI and high-contrast
monitors and printers. This may not be a "big deal" YET for most consumers
who don't have access to this technology now, but this is a big deal in the
medical/government field.
Tons of new management/administration features: a new event log (which
supports XML and forwarding events to a specific server) that is much easier
to use and search through; much more powerful and performant performance
logging (tracing, counters, wmi, etc), enhanced task scheduler (example: you
can have a task run whenever a certain event is logged via the event log),
enahnced offline files (syncing to a server only sends the CHANGES MADE to
the files over the wire - roaming profiles just got a whole lot quicker).
Of course, these are only some examples that show specific cases for
upgrade. There are many other enahncements in Vista.
Reliability and performance are greatly improved (for example, many drivers
can now run in user mode, including the display driver, meaning if they
crash, the system doesn't go down - it just restarts the driver and the user
has no idea there is a problem; also, the file system and registry support
transactions now [applications have to be programming to use this feature],
meaning if the power goes out your applications can recover their
files/registry settings to a usable state).
If you think that the new start orb is the only thing new in Vista, you are
sorely mistaken.
Here's a good website that glazes over some of the most significant
technical changes:

And the most prominent end-user visible features that most people are aware
of:

So ... does this mean you should upgrade? I don't presume to speak for
anyone but myself. I think one should look at the benefits vs. the cost and
decide for themselves.
