Yes it is a sensible argument!
If you have designed an app for the small iPhone screen it will scale up 2x on the iPad screen. Most apps look ugly -- bigger but ugly, with a lot of wasted space!
The controls are too big, the text is too big
-- lots of jaggies because no anti-aliasing.
There are exceptions, but you usually have to rethink an app when you move it to the iPad.
The mail app is a good example:
On the iPhone, it's a single column table (scrollable list) with a drill-down:
Mailboxes-->mail summary-->mail detail (the email message)
On the iPad, it's a two tables (side-by-side scrollable lists) with a drill down on the left list
Mailboxes-->mail summary left column or popup (portrait)
mail detail (the email message) right column or underlay (portrait)
The controls and text are about 30-50% larger than on the smaller screen.
If you started with the larger format and scale it down to 45% of the original-- it could easily be less usable than the iPhone.
Samsung, on their Galaxy Tab appears to have provided all the basic "system apps" (mail, calendar, contacts, browser, etc.) where this might be a factor. What they appear to have done is something between the iPhone and iPad -- something specifically scaled to the 7" format.
This, at least, looks OK. Any other Android tablets that do not
provide their own "system apps" will have them disproportionate to the size of the screen.
