Is This .Info Any Use?

The question of '.info' domain name extensions often crops up.  Are they any use?
After me thinking not, it was revealed that one of my own .info domains was doing OK so, perhaps it was worth investing in the .info extension that cost less than $1.00 to buy for a year.
A '.com', however is around $10.00 for the same length of time.
Does Google think that anyone who purchases a .info domain are just planning to have 'thin' sites that are weak on content?
To test out my theory, I used a small program written by Internet expert Martin Avis.
My main .info domain was 'Amusement Arcade'.
The program tested which extensions were found in Google's hot 100 listings with a separate list for the first page.  Here are the results for my keywords:

The keyword: amusement arcade is showing 125,000 results in Google (US).

On the first page of Google's results

the following domain suffixes feature:
com: 9
org: 1
In Google's top 100 listings
the following domain suffixes feature:
com: 66
org: 5
gov: 1
net: 8
info: 2
us: 2
cc: 1
in: 1
 
Only two of the top 100 are .info and none on the first page.
But look at the phrase 'Internet Marketing':
The keyword: Internet marketing is showing 28,900,000 results in Google (US).
On the first page of Google's results
the following domain suffixes feature:
org: 1
com: 9
In Google's top 100 listings
the following domain suffixes feature:
org: 1
com: 96
So, I think that we can determine that .info are really not any use UNLESS they contain the EXACT keywords in the right order of what the person is typing in to Google.
Stick with .com everyone, if you can.
