An interesting overview of the different cloud matching services - interestingly the Apple iTunes Match (the most expensive option) will UPGRADE the quality of the music it matches for you, even if you have a lower quality version. Otherwise, as you make up your mind what to do, you'll want to read this article.
The Amazon mp3 store and cloud player is another option for your music. If you've been buying music from Amazon, you already have some music in the cloud - I have to buy it on Amazon for the senior tribute movies I make for graduation because iTunes has so much DRM protection that it is hard to find music that I can use in the movies.
I've been looking at cloud based music services - the Lifehacker people seem to recommend Google music (even if you have an ios device) although if you have more than 20,000 songs you may want to go with Amazon music for $25 a year for 250,000. iTunes Match is $25 a month no matter how much you have and will store everything in the cloud but it is expensive. As for me, I'm going to be setting up google music. Interestingly, some of the coolest gifts we give ourselves are apps in the cloud. this article shares all about Google music.
Caldav is what lifehacker recommends as an alternative to Google sync (which is going away January 31). I've been searching for an alternative to help our office manager figure out what to do. Lifehacker referenced this on their podcast from this week as still being currently the best way to replace Google calendar sync.
The biggest privacy offenders (hat tip Lifehacker podcast) include Facebook, gmail, MSN Live, Skype, Twitter, Dropbox, Google Plus. This demonstrates whoch internet service providers share your personal data without an official court order. If you look at the infographic, you'll see that Facebook is more than twice the second offender, gmail. Many concerned about privacy are moving to services like PATH for just that reason.
Guardian has pulled its social media sharing app from Facebook (it is my understanding Wall Street Journal has too as discussed on the TWIT.tv - this week in tech show). As I'm wrapping and washing clothes, I'm listening to Twit on the iCatcher app to keep up with things. Many like the Downcast app, but iCatcher has always worked for me.
