You're making the all-too-common error of conflating "unlimited" and "infinite". "Unlimited" means the provider is not imposing a limit on how much you can use, but you are still constrained by the infrastructure involved--in your Netflix (Qwikster) example, that constraint would be the postal system. In the case of streaming, the constraint is the (e.g.) 720 hours in a 30-day month (you obviously can't watch 5,000,000 hours of content in 720 hours). In the case of Internet service, that constraint is the speed of your connection (there's only so much data you can download given your provisioned bitrate, congestion on the network, and your network interface).
If, no matter how much you use, the provider will not cut you off or tell you that you used too much, then you're getting unlimited. If you want infinite, you'll need to make the speed of light infinite. In this universe, c is the limit, no matter what you do.
I leave you with a Fawlty Towers quotation:
Basil: "The sky's the limit!"
Sybyl: "22 rooms is the limit."
In practice an Android phone with a locked bootloader (and running a closed-source Android version) is as closed as an iPhone.
No. First off, all versions of Android that run on phones are open-source. Even on tablets, though, where Honeycomb is not open-source, you're free to run whatever apps you want without having to get anyone's approval. On the iPad, you can't (without jailbreaking). That, to me (and I think to many others as well), is the most important distinction.
This is not true (in the US). The only copies you can have are ones you make yourself; downloaded copies are still illegal.
Not like you're going to get caught.
What business is Google in? Indexing content or providing content?
They are in the advertising business which is supported, to a great extent, by search. Indexing content and providing content are two complementary approaches to delivering quality search. Recently, we've seen much more federated search on Google--in other words, combining results from different resources. For instance, a search for Apple will give you results from the web index mixed in with results from image search and product search.
An example where one of the elements is content that Google provides rather than indexes is Maps. Sure, Google could index web pages that have maps on them (and they do), but the user experience is far superior when the search engine can just provide the content you want without the need to perform extra clicks
The researchers and engineers are concerned primarily with making the user experience as satisfying as possible, and providing relevant content is part of that. If the users are happy, they'll keep coming back, thereby generating ad impressions and making money for Google.
That begs the question: Why weren't you being fully careful?
(For those who don't know, "begging the question" is a type of logical fallacy where the conclusion is assumed in the proposition's premise. The correct phrase here is "raises the question". Alas, it seems that this battle has been lost; nobody seems to know what begging the question actually is anymore.)
I program, therefore I am.
