Talking about compatibility, i feel that its increasing. And with new versions of software coming out very fast that are fully compatible with Vista, the compatibility problems are not going to last. Ya, as i wrote before, i too was at first sight was very, kind of unhappy to see some of my really close to heart programs not working properly in Vista (i must mention HTMLGate html editor, its not in development now and its last version quits with an error at startup on Vista). But then, the weightage i give to the security, stability, performance and innovation that i personally feel i am getting with vista, the wise move was to move on. And there came the express editions of Visual Web Developer 05 and then 08. All my problems were solved. These are really good, standard compliant HTML and javascript editors and with vs 08 express you also have full Javascript intellisense, so why will needs anything else anyway. Secondly, since i have professionally shifted to .NET, i mean the ASP.NET+AJAX+Silverlight combo for web development, these things work great, although at work i use full version of VS, obiviously. And by the way for PHP development the version of PHP Designer by the same company works very well with Vista, and there are other great products for that as well. As a sidenote, most of the problems that i had with my programs were solved by running them in admin or WinXP SP2 compat mode.
