1) Microsoft can do no wrong and is right and admirable to pursue dominance by any means necessary.
2) There are NO other viable computing/development platforms.
3) That successful marketing by Microsoft has not influenced their computing/technology choices.
The term "Billion" is a combination of 'Bill' (Bill Gates, Microsoft co-founder and it's most recognizable face) and 'Legion'. So, "billion" = "Bill's Legions." Also, it's a play on the idea that such people eagerly add billions of dollars to Mr. Gates' fortunes.
"My life as a Billion has not been without it's share of viruses and installation headaches."
"No self-respecting Billion would be caught dead using a Macintosh."
