I'm impressed with better fonts. Only my hardware still lacks, my display is 1280x800 pixels. And however I seem to muck about with settings it never feels entirely comfortable. Aliased bitmap fonts in a terminal are probably easier on my eyes. Web sites are quite horrid to look at. Which seems counter intuitive. I don't really miss my CRT and low display resolutions, but I think for a 12 inch monitor more resolution helps, especially with anti-aliasing. But this stuff is superficial compared with actual functionality.

I think the articles comments about poor calendar and contact applications really highlight missing functionality. Outlook did well I think because of the calendar integration. Even the most architecturally stunning systems aren't worth much without a great application eco-system. That's no slant on Linux.
