Don't look now! WordArt in Word 2007
If you've tried the new WordArt tool in PowerPoint 2007 you've probably discovered how neat it is. No more bent words in putrid magenta colors and instead, theme aware text that looks great for headings and which will change color when you change the Theme.
Try the same thing in Word 2007 and you're in for a ghastly surprise. WordArt missed out on getting a makeover in Word 2007 and, instead, it's the same application it has always been - functional but requiring a lot of additional work on behalf of the user to make it look even half good.
Here's hoping that the next implementation of Word, whenever that appears, finally does away with this and gives us WordArt that is usable and as functional as that in PowerPoint 2007 and Excel 2007.
