Is Vista a worthwhile OS for the enterprise? Hell no. System requirements are far too steep for most medium to large organizations, since most of their machines are probably 3+ years old, recycled from employee to employee, and loaded with the bare-essentials to begin with. Vista represents a greater cost beyond simply purchasing OS licenses. The advantages Vista offers over XP are not compelling enough to an enterprise environment to justify buying all new systems. I bet you won't see Vista in large, non-tech, companies for another 5 years. XP still suits their needs.
Also realize that many
business critical applications will not run on Vista. And probably will not for at least a year or more. So, there's DEFINITELY no way those users can/should upgrade.
Is Vista a wortwhile OS to Mom & Pop User? Honestly, it's no better and no worse than XP for people who just want to surf the web, send email and type letters. To the average user, aside from UI changes, Vista isn't actually a step backwards in terms of stability. Should these people upgrade their existing systems? No. However chances are they'll have it on their next new PC from Dell, HP or Gateway. That's fine. Those users won't suffer too much (or any more than they did transitioning from 98 to 2000/XP).
Technically, that's all well and good. But there's no reason that the new OS should cost 2+ times as much as the prior one (XP)! Can you say "bloatware"? I knew you could.
Is Vista a worthwhile OS for the tech enthusiast? Well, if you're not going over to the OSS side of the fence, Vista packs a lot in for the technophile to play with. If you like having new gadgets to fiddle with, and want to be ahead of the general curve on tech, then Vista is probably something you're moving to soon, if you haven't already. You won't have trouble relearning the UI and functionality, because chances are you've had to relearn that dozens of times as you bounce around between different operating systems (Linux, MacOS, Windows etc.)
Possibly true. However, due to increased product activation/stricter licensing, one can no longer reformat, reinstall, swap hardware, etc. which the tech enthusiast does quite often. MS is just getting more greedy, and including more crap into their OS than they need to.
Vista is far from "ME2" WinME was a horrible OS that didn't actually function properly even without any apps running. Vista is a suitable addition to the Windows line, but right now there still isn't a compelling reason to move over.
It's not an "Me2" from a functional standpoint... unless you take into account backwards compatibility (which as both a business user and a tech enthusiast you SHOULD). It's a "Me2" from a sales/marketing/etc. standpoint.
Overall review: Vista is an extremely overbloated, DRM-infested, horribly overpriced PIG.
