They seem to be starting out with some good features, but are missing many. Zoho is closest to providing an online office suite that compares anywhere near Microsoft Office. Adobe is starting out with a word processor, document sharing ability with a generous 5GB of space, a document to PDF conversion tool, and a really nifty web conferencing application.
Just a couple bullet points:
- Look & Feel: Wow – the Flash based interface is impressive
- Consistency: Needs some work, changing applications launches too many windows
- Integration: Very little between "applications"
- Functionality: Depends on feature – some are quite rich, others very basic
- Features: Document sharing, Word Processor, PDF Conversion, Web Conferencing
Overall it’s a good start. There is a long way to go to compete evenly with Google Docs & Spreadsheets, but then Google doesn’t have a web conference tool. It’s not going to compete with MS Office, or any of the others for some time. With that said, however, if you want to convert some documents to PDF, host documents that you can link to in email or from a website, or a decent free web conferencing tool, it might be a good adjunct to your current solutions.
