One week ago I switched on ClearType on my desktop system. The system is a dual head system with one crt and one tft connected.
I never heard about ClearType before I got my Axim X5v PDA which has ClearType enabled by default. The reading experience on that device is very nice. Everything is very smooth.
Now I'm using ClearType on my desktop and this is my experience:
Reading E-Books is really great and you're not getting tired of reading many articles.
The desktop looks crappy. The Font of the icons is not suitable for cleartype. I have to mention, that I have a holiday picture as background image, but also with the plain blue background there are shadows around the text.
Coding with Visual Studio is fun and all the text here looks very nice and smooth too.
I have not noticed any performance loss on my machine.
I think I leave ClearType switched on if there are no negative site-effects.
What's your experience on ClearType?
