I just got a brand new MacBook Pro 15' (thanks @ldubost!). It was a needed upgrade on my old MacBook 13' (yeah, the one that got fish food spilt on it).
What really amazed me was how fast I was able to perform the switch while suffering almost no productivity loss whatsoever (besides the time needed to install a couple programs). I was able to start using it without transferring any data from my old computer.
All the stuff I need is on our intranet or in my mailbox. I was able to complete a new deal with an US customer without having access to previous versions of the PO I had sent them since the PO itself is a wiki page on our intranet.
Even stuff that used to take me a while, such as transferring my music, is now possible without hassle. I'm a Spotify Premium subscriber thus as soon as I had downloaded the client I was able to access my favorite music.
I eventually transferred some of my old data to my new computer, but I didn't even need a cable to do that - I just downloaded a ZIP from the Backblaze unlimited online backup service I use to backup my computers.
One of the key points I'd like to highlight is how easy it was for both of those services to turn me into a paying customers once I had been able to get taste of how awesome their services were. By the way, I'd happily pay for Posterous as well if it ever introduced a premium version!
While there's nothing groundbreaking about all this, I thought I'd share the experience as a testimony of the fact that the cloud promise (subscription-based online services) is getting more real every day.
