Worth mentioning Gnumeric, a nice and clean spreadsheet counterpart to AbiWord.
Imagine if they had put their effort into it though? Almost certainly they would have been at the forefront of desktop options and a good likelihood as a candidate for corporations.
All in all, GNOME Office didn't happen. Some bits did, though. AbiWord was always broader than GNOME. And Gnumeric is great IMHO.
And people see the future in the cloud.
And Abi as a company was long gone by that time.
Desktop software just isn't the same as sellling consulting, trainings or SaaS licenses behind browser paywalls that server based software enjoys.
