Granny Smith would be pretty used to things looking wrong on her 1024x768 laptop - besides, a resolution that low indicates that the laptop is positively ancient. Would she be really looking to replace the OS on it? Even if she were, is this demographic even remotely large?
>His complaint is very valid in my opinion. Imagine Granny Smith being sent to that page and opening it on her 1024x768 notebook.
Why? What's the purpose of sending "Granny Smith" to that demo? She going to be really excited about the new OS and install it herself? Even if you do, she emails you and says it didn't work, so you...do what you did before. Live cd? Have a discussion with her? Let her try yours?
The online demo is not the only method of trying the OS. It's really not even a true method. It's a marketing tool. Not something you would send Granny Smith.
...and then what? She ends the idea of installing the OS? No, she probably tells you (for whatever reason) she doesn't understand what she's looking at. And your response is what; to just quit? Tell her to use her current OS?
My point? The online demo isn't the end-all of the Ubuntu preview. Stop treating it like it is.
Finally, ask yourself, am I making good points or trying desperately to win an internet argument.
Christ, give it a rest. Canonical should definitely not be targeting Granny Smith, not yet anyway. Power users dissatisfied with Windows or MacOS are where the action is for now and the foreseeable future.
(Here, I use the term 'power user' to mean e.g. anyone who has looked at the device manager in Windows.)
