The idea is to sequence each portion of the genome many times over. With enough redundancy you can detect these errors, so your final annotated copy would have a much higher accuracy.

This is a new feature in the soon to be released Gimp 2.4, check the release notes at:

Aye, it looks like a lot of the "useful new" features offered by EIO are already available in OpenOffice, such as suggest-as-you-type.

I think the big clincher for me would be how it interprets MS-Word shapes and drawings, as that's the only problem I've ever had with OpenOffice.
