XP
For all the naysayers out there, and all the pundits, the end is in site for XP. I've been using Vista now for nearly a month. The other day I went through all my old applications for XP and junked most of them.
It's time to say goodbye. Vista is that good that it's going to change the landscape. Why? The productivity gains are simply to big to ignore. Even at this early stage everything works.
What's the must have feature - SEARCH... yes that's right. Good old search. Microsoft have this one dialed. If I want to find something all I do is hit the Start button (now called the Perl) type a few characters and a list appears. Usually what I want is at the top already highlighted. I simply hit enter and I'm running. No more mouse clicking.
This search is also tied into Office 2007. In Outlook all you have to do is type a few characters and it highlights all the instances in what seems like a nanosecond. If they tie this kind of search to Live I think you will see a fundamental shift in how people use search.
As for the rest, Vista is fast, it's fast, it's fast. Did I say it's fast. Now sure I have a year old Sony Vaio 3Ghz with 2GB of RAM (Vista gives it a rating of 3.4) - however it still cranks. The new machines coming out will start showing numbers above 5.0 and what you see and feel will be amazing.
Finally what about the User Interface. Well I love it. And I've had the opportunity to test drive it against Mac OS 10. Give me Vista anyday.
So as Maria Von Trappe would say, "So Long, Farewell, It's Time to Say Goodbye" to XP
