Of course people are upgrading from XP to 7 - if they are upgrading at all. Who upgrades from Debian to Windows? Or, Solaris to Windows?
Oh - 6 XP users upgrade for every Vista user? Surprise, surprise!! Probably half a billion people in this world THOUGH about upgrading to Vista, but decided not to when Vista proved to be such a bomb.
Let's remember, Vista wouldn't run on old equipment, while Win7 runs on anything over a gigahertz with a gig of memory. A lot of XP users COULDN'T upgrade to Vista!!
Linux, therefore has 13.37% of the "non-MS market".
If that isn't proof Linux is awesome then I don't know what is.
You can jailbreak if you want but you should be aware that your phone is no longer secure once you do that and any personal information that you store on your device can be compromised. The BSD jails prevent other applications from accessing data that does not belong to them.
Read the link. 5 pages of errata, and that's just headlines. Modern processors are very complicated, and they will have bugs.
The major difference between Intel and AMD when it comes to errata is that Intel learned its lesson about secrecy from the Pentium FPU fiasco. Since then they have had a very open approach to processor bugs. AMD hasn't had such a PR disaster and isn't quite as open. That doesn't mean they are particularly less buggy.
Without that information, all you'll get is a bunch of people suggesting their own pet projects.
Even if you just want to learn and play you might want to have a goal. Do you want to learn to administer ZFS? You seem to be fixated on it.
