Well that just depends on who you ask, and if the person is myself then you are going to get the following four reasons why I personally would not even bother with Windows Vista.

…Windows Vista won’t run Microsoft Word any faster, won’t make your presentations look any better, and if my own experience is any indication then Vista is not going to make managing your PC any easier either…. To make matters even worse this *new* version of Windows is really just the Windows Server 2003 kernel in colorful clothing with some snazzy new mini-applications…. Additionally, my own informal tests on my Macbook Pro seem to indicate that Vista upgrades will likely run existing applications slower than XP for many folks forcing the purchase of new hardware just to “keep up”. Bottom line; Vista does not add any substantial new features for new or existing Windows users and may even be a significant reduction in speed for some users who dare to upgrade from XP on today’s hardware.

…One of the first things you are going to notice is the new interface which is a major case for the bifocal lens thanks to the excessive use of transparency. Unnecessary eye candy is everywhere, and seems to not add or enhance any features that might make users more productive. No well thought out GUI tricks like OSX’s expose here, just pure bling that quickly becomes annoying on all but the fastest PCs. The bottom line; Windows Vista does not bring anything new to the table other than more gizmo-style features that only serve to get in your way when you are trying to actually get some work done.

…Security will still be a major problem - Since Microsoft decided not to build Windows Vista on the longhorn kernel (which was rumored to be a complete rewrite, or close to it) they ended up leaving many of the known problem areas of Windows XP (and other previous versions) still in place…. This layer is visible to the user in the form of dialog boxes that pop up every time you require “administrator” or direct access to system resources, something that seems far too common on the Windows platform…. Bottom line; constantly annoying pop-ups intending to improve security will actually result in even greater problems as users begin to blindly click “Ok” even more than they already do now.

…The reality is that you can do everything promised by Windows Vista in Windows XP today with less hassle and in most cases faster than you could in Windows Vista on the same hardware. If you already use Linux or Mac OSX then Vista is not going to impress you anyway so don’t even bother taking a look.
