How long has MS Office been around? I thought so...now, how long has OO been around? OK. How many people work on Excel every day for 8 hours a day for 10 years? Now, how many people work on Calc every day for 2 hours a day for 4 years? OO will improve, but it needs T-I-M-E. Actually, people are working on Writer more than Calc, because it's more important to the desktop user. Hey! They just had a job opening. Maybe you can join. ;)
