They have a decade of market and user experience and they have worked damn hard to seduce people into reliquishing control of their data to Redmond. I'm hoping Gnumeric has a reputation for getting the job done. That is something to be proud of. In fact they have been showing gnumeric doing graphs for the past 2 years. What's the holdup.
Spreadsheets are useless for many without graphs.
I know we need them. Each time an interesting sample sheet comes in requesting just one more feature before they can switch over. With luck the increases in the developer strength and my public commitment to freezing in July will force the issue. Each release gnumeric gets better and better. Builds with no pain, runs smoothly, works wonderful.
