What sort of multimedia features? I have Vista but I haven't really taken advantage of what it can do
I have the Home Premium version, and it comes with Windows Media Centre, which is great if you don't want to look for a third party app. WMC also doesn't require an infrared remote control port to install (like Frontrow on the Mac - darn I wish I could use it on my iBook).
The Explorer interface, for browsing files, has been enhanced to not only show previews etc (something that Apple has prettied up on Leopard), but EXIF data which ties in with MS's equivalent of iPhoto - Windows Photo Gallery. It's a very smooth way of dealing with photos. Unfortunately I can't use iPhoto on my Mac because it insists on making duplicates of all of my existing images, and then duplicates them again whenever I make a change. I have a couple of hundred gigabytes of photos, so this isn't feasible. Windows Photo Gallery doesn't make duplicates when you launch it for the first time. I don't know if it does when you make a change to a file - I tend to use Photoshop Elements for that stuff.
You can also launch some amazing slideshows directly from Explorer, with all sorts of special effects and transitions. Burning DVDs is still not quite as nice as it is on my Mac though. I haven't explored Vista's DVD or movie creation software yet. For music, I use iTunes so I can't really talk much about WMP's integration in the OS.
Playing videos from Explorer is also much improved. It lacks the flair of Leopard's Finder when it comes to this, but it does everything just as well, and also shows useful information like bitrate and frames per second, etc.
But anyway, I'm kinda rambling. But like I said before, I really hated Vista at first, but now that I have some content in it, ie, music, photos, videos, it's really coming into its own.
