Paul Thurott takes a look at the latest Windows Vista (and has some screenshots) beta and has some criticisms.
We've been playing around with it as well and our initial excitement over Windows Vista is starting to turn into concern as we remember where Windows XP was at this stage of development -- it was in better shape.
The issue isn't just the bugs (which there are more than one would expect) but significant compatibility issues combined with Microsoft not making it clear whether they're going to live up to their performance expectations. For instance, the new Aero glass UI isn't fully hardware accelerated from what we can tell. Resizing windows or doing anything particularly intensive on the screen eats up a lot of CPU. CPU? It's supposed to be using the video card (WindowBlinds 5's performance gains don't eat up all your CPU on XP because it's using the GPU instead of the CPU for instance).
The state of some of the new goodies is problematic. The Sidebar, which we're excited about as a concept, needs better content if it's going to be on by default. Microsoft has broken the LogonUI elements which many programs, including many of ours, finger print readers, etc. made use of in order to do their magic and has provided no work around, no new API, nothing to resolve it despite developers asking for a resolution.
Bugs get filed and then marked closed seemingly arbitrarily. And many existing programs, which should work fine on Vista, just don't work. Right now, even DesktopX is not working on Vista. Why? We don't know. We'll find a way to resolve it long before release but it's these seemingly arbitrary compatibility issues that give us pause (let me put it like this -- WindowBlinds works on Windows Vista which you'd think would be a much tougher thing than DesktopX to get working).
It's too early to say that Vista is having serious problems. But time is running out for Microsoft to provide a build that looks like it's remotely ready for prime time. We'll be traveling to Redmond next month to talk to Microsoft on these issues and more.
