>Google docs is fine for maybe 80% of use
Which is able to undercut a good portion of Microsoft's market.
Keep in mind the original comment I was replying to:

MS Office is on its way to becoming redundant to the majority of users. The price is going to be less and less justified in the near future as Office loses its reputation as a crucial piece of software (at least for the average student/employee who doesn't need to perform very specific formatting or perform complex spreadsheet calculations).
Even if the average person doesn't need MS Office for their own work, there will always be this one prof that emails homework assignments in MS Word format, or the accountant that sends you an Excel Workbook to fill, etc.
Yes, if you're a programmer you can probably get away without Office. But for many people who collaborate with others, having a copy of Word / Excel / Powrpoint is still pretty much essential.
(Side note: I hate people who use Google Docs for their presentations. "Oops, I guess I shouldn't have pressed the back button". "Sorry for the delay, the presentation should load any minute now". "Could everyone please turn off Wifi on their phones so the speaker can open his presentation!")
I think my point was I think that even a typical student will find google docs lacking, but perhaps it is usable enough.
