Jeff,
I never claimed it was full.
It is "beta" and with Microsoft, that means something prior to "alpha" anywhere else.
Or earlier.
I've been an official beta-tester for Microsoft on a few occasions through the years, take part in their public beta offerings frequently.
I just thought it might be fun and interesting to participate in the final creation of a software programme which, ultimately, will be used by 50% of the market.
Whatever one may think of Microsoft, they really do pay attention to the feedback at this stage. I was one of several people who did not like the original Longhorn programme listing (be thankful you were spared it) and it was big, big, the very best thing internally at Microsoft. When the complaints from the beta testers hit a certain percent, they reworked it and we got the usable interface we know from Vista.
Now, both Apple and Microsoft make a lot of software available for free when it hits end of life. Back when ClarisWorks belonged to apple, they offered some outstanding versions for free - including, ultimately, ClarisWorks 5 which, at that time was rated by the journals which mean something as being a serious alternative to Office 97. You can download Windows 98SE for free from Microsoft (not sure why you would).
For those who really don't like the thought of buying or using Office 2007 or 2010, the 'viewer' versions for Word and PowerPoint and Excel worksheets as well as (limited) Access confections are all free, load fast and both portray on screen as well as print the file exactly as it would have been in the full programme.
I've edited 17 term-papers written in doc97 and docx format (told my students not to, but some don't listen, 0.5 off their note for that) in this beta as well as created a few PDF-As. Only larger project so far was a flat database which I set up in Excel. No crashes or missteps so far and the commercial add-ins I use for Office 2007 all work just fine.
It's a beta. But, gosh - for someone like me who enjoys playing with new things, learning new programs has to use Microsoft Office and really hated the 2007 version passionately, it's felt good. Sort of like when NT3.51 got the New Shell.
Probably the most useful thing will be the tie-in to cloud computing. Or, maybe, the light-version which will make it possible to take the document you are working on, put it on a thumb drive and open/edit in the Office 2010 app. you were using anywhere, regardless of whether they have the Suite installed or not.
I began using StarOffice back when they were in Starnberg, just down the road from me and I called company headquarters, a local call, when things didn't work right. Today, as OpenOffice, it is my favourite programme.
Softmaker has had their ups and downs (was primarily written by one person in the beginning!) but does a pretty decent job of incorporating filters which actually work with Microsoft's concept of adhering to "industry standards". They've yet to see an ISO-Anything which they didn't feel needed tweaking just a mite...
