I used to use Windows until I switched to Mac in September (new PowerBook

). We were using Windows 98 but have just got a new home PC - Dell with Windows XP.
I have to say that it is no longer justifyable to say that Windows crashes all the time. XP simply doesn't. I know OS X doesn't either, but I'm glad they've finally fixed that on the Windows side (goodbye '98 and blue screen of death!).
What I don't like about Windows, and why I won't be looking forward to Longhorn, is Microsoft's whole design philosiphy! Microsoft simply doesn't understand the user interface. It's not just Windows, it's in everything they ever make!
For example, try going to the help centre on Windows XP. You get a dialog box with about 200 questions on it. It was so overwhelming I shut it down immediately. In contrast, Mac OS X help is simple and uncluttered (and now fast in Panther!). I then had a look at Windows Movie Maker 2. What a POS. Then look how simple iMovie is. (I hate the fact the Windows app makes you work in low quality WMV only!).
I hate all the sidebars on the left hand side of windows explorer windows as well. They are new for XP and you can't seem to get rid of them. Apple's 'copy' (the Finder sidebar) is much simpler and nicer by comparison.
Microsoft seems to love 'Wizards' as well. Plug a USB flash drive in and all these wizards open up with complicated options. In Mac OS, the drive just mounts on the desktop where I can see it. Simple.
I wish Apple would build certain bits of Windows' functionalilty in though. Some better contextual menus and the like. There are some Windows features I miss.
I guess this has turned into a bit of an anti-XP post. Windows is all right when you get used to it, but I just think Microsoft needs to try and think before designing anything. Why can't they design a simple interface with anything, like Apple can?
