We all call them Kleenex, but they are facial tissues. If someone had tried to trademark 'facial tissue' we would be in the same ballpark here.
The most defensible mark is a fanciful one, that is a word which does not otherwise exist (Kodak, Xerox, Pepsi, etc). Afaik, Kleenex actually is the best possible name one could choose to associate with tissues, since it is entirely fanciful (and Kleenex company has done a good job associating their name with tissues). As an aside, it is possible for a diluted mark to lose its protected status (such as with Bayer's "Aspirin" analgesic).
These marketing people might as well start trying to trademark things like 'desk' 'pen' or 'screen'.
Netbook would probably fall under the "Suggestive" trademark category (the third most defensible category, behind Arbitrary and Fanciful). Net and Book both exist as words, but were previously not widely applied to this sort of device.
So, in conclusion, "Netbook" is nothing like "pen" or "desk," as far as trademarks go. Neither of these examples would even be registerable, unless they were referring to something they weren't (you could make a ketchup product called "DESK" or a cell phone called "PEN").
With X-Box, you need to hack the HD in order to run any other software. With the PS3, you simply go into the system menu and select (install other OS).
Sony's just as evil as the next company. From what I understand, they declared the PS3 to be a "computer system" as a means of avoiding tariffs in Europe, and to do this they needed to offer access to the OS. Plain and simple. They tried this with the PS2, but it didn't offer access to the OS, and thus failed the test (as I am led to believe).
"Tie-In Sales" Provisions Generally, tie-in sales provisions are not allowed. Such a provision would require a purchaser of the warranted product to buy an item or service from a particular company to use with the warranted product in order to be eligible to receive a remedy under the warranty. The following are examples of prohibited tie-in sales provisions. In order to keep your new Plenum Brand Vacuum Cleaner warranty in effect, you must use genuine Plenum Brand Filter Bags. Failure to have scheduled maintenance performed, at your expense, by the Great American Maintenance Company, Inc., voids this warranty.
They are arguing that tieing to AT&T, and then firmware releases bricking phones that have been unlocked to another carrier is an illegal/tortious act on the part of Apple. They allege Apple has told customers that downloading of unapproved software (but software that should be legal to install, under the MM act, imo) will void their warranty. Furthermore they have a vested financial interest in "approved" software from the Apple store, and obviously refuse to allow unlocking software to be included in that store. They refuse to provide customers who have lawfully canceled their AT&T contracts with unlocking codes so they may use their device with another carrier (again, covered by MM act). The list of allegations goes on. Full text of 15 USC Chapter 50, which is the section of the statute they have sued under (although I believe Title 16 - Commercial Practices, Chapter I - Federal Trade Commission, Subchapter G - Rules, Regulations, Statements and Interpretations under the Magnuson-Moss Warranty Act, Part 700 Section 102 also deals with warranty denials, text here).
They are alleging illegality on the part of Apple in that they monopolized the market for iphone applications, and also apple+AT&T for voice and data service monopolization. And of course the alleged illegality I spoke of above (services ties, denying consumers the ability to break these ties, pushing software updates that intentionally break the phones of users who have circumvented product ties, and then denying warranty coverage for these affected users)
I hope that was somewhat helpful.
