This is a rather superficial reason to start such a project.
Mathematica is non popular because of its syntax, it is popular because of its extensive library, graphics capabilities and documentation.
If you want to make free software packages more competitive compared to mathematica, the best way would be to work on extending their libraries, documentation and graphical capabilities, not increase the fragmentation by starting yet another package from scratch doing the same thing just using a slightly different syntax.
For all intents and purposes, from an user's point of view, this project is as a waste of time as writing yet another scheme interpreter.
You'd be surprised at how many engineering companies (research and otherwise) use Excel. I'd argue that it is used more than Matlab or any other programming language/environment in some fields (like Mech Eng).
Now that is just a small subset of all the little corporations that use it for bookkeeping and what else (those could probably get by with libreoffice) and every other major company in the world.
Microsoft was also smart in moving to docx and xlsx because libreoffice doesn't support that very well and now has an even better reason for people to avoid switching, I'd like to assume they don't support the open formats for this same reason.
I pay for fastmail, but there was a workaround where if you signed up for GAE with your domain you could get 1 free account. (Don't know if that still works)
I believe microsofts offer costs similar to the google apps.
It isn't the scantily clad women necessarily it is that they are really the only registrar people can think of when they want to get their own domain because godaddy is the only domain registrar that advertises on tv.
It's not just you, I recently used a SIII and it is giagantic compared to my iphone 4 which makes it difficult to use. (And I don't have stubby fingers).
I don't think it's a product of screen size, I think it's more a product of what phone (form factor) you own/started with.
My first smartphone (late to the game) was a Motorola Droid Razr. It's a little smaller than the SIII, but being my first phone, I just became accustomed to the size.
I use friends' iPhones a lot and the first thing I notice (other than just one button) is how small it is. Those same friends struggle with the enormity of my device.
I think it's a similar context switch from Windows <==> OSX. I think people can grow to like either of them, but using one after years of using another makes it seem unwieldy.
And those that do pay do get support http://support.google.com/adwords/answer/1385067?hl=en
And I believe there is some support for apps for business.
