Ubuntu 9.01, and I've just upgraded my laptop. I'll have notes on that shortly. For now, I want to take a (skeptical) look at Ubuntu One, Ubuntu's Cloud Computing effort.
There are two plans available. You can get two GB for free (except the sign-up information you give them) or 50 GB for $10 a month.
My first caveat with cloud computing is: I don't want to store sensitive data on someone else's servers. They have less incentive to keep it private or accessible to me. Also, legally, they, being a third party, may have to cough it up where I would not have to.
Then there is the data you give them on sign-up. You may or may not care about that data or what Canonical does with it.
Then there is the thought that the 2 GB for free will fill up very fast, and is likely a loos leader for the 50GB for $10/month plan. Let's look at this a moment. For $10 a month, in a year I'll shell out $120. That will get me a terabyte plus external drive, or 20 times the storage. I can encrypt that myself, and use it for off-site backup. I can buy two drives (paid for in two years at the same rate) and rotate them, which I've been doing for over a year. And at the end of that year or those two years, I still own those two hard drives.
On the other tentacle, you can share your two or 50 GB with other folks much easier than you can share that terabyte drive. OK, rotating two drives to off-site storage locations means getting up out of my chair and walking downtown. O! The horrors! I might actually get some exercise! I might have to interact with someone in meat space!
I suspect that, in addition to being Canonical's entry into the cloud computing foofooraw, this is also part of Canonical's effort to claw back some money from all those CDs and all that software and all that infrastructure (like Launchpad) they've given away free.
