Ubuntu have two horizontal tool bar, not just in 10.04, it used to be in all previous versions. It waste vertical space in monitor. Windows done it perfectly with one horizontal task bar having everything. Why Ubuntu waste screen space with 2 bars ?
Another problem i face is with TV Turner card, i got it working in Ubuntu 10.04, but it won’t work all the time. Sound some times it work, some times not. Look like Ubuntu sound need to be improved.
I used text to speech a lot in windows. Ubuntu come with espeak, sound quality is too bad, very difficult to understand. On windows, there are many good TTS available.
