Last month, just one week after IBM announced it would help with OpenOffice.org's development, the company released Lotus Symphony, an office suite based on OpenOffice.org code. I found a lot of slick features in Lotus Symphony, but I worry that Symphony could affect the OpenOffice.org community adversely.
Lotus Symphony includes a word processor, a spreadsheet program, and a presentation tool. You'll have to register with IBM to download Symphony. Installing the office suite is a no-brainer, and requires 490.5MB of disk space.
Symphony doesn't launch any faster than OpenOffice.org.
