Dropbox has decided to call it a day on their photo management app Carousel and the email client Mailbox.

Building new products is about learning as much as it’s about making. It’s also about tough choices. Over the past few months, we’ve increased our team’s focus on collaboration and simplifying the way people work together. In light of that, we’ve made the difficult decision to shut down Carousel and Mailbox.

— Saying goodbye to Carousel and Mailbox by Dropbox

To be honest this isn't going to have any impact on me. I didn't use either of these services, but what's interesting is that we're losing another good email client to a tech giant. I didn't use Mailbox myself but it's clear from the many messages and comments that lots of people used and they rated it very highly.

I remember using Sparrow for a few months as my email client before they were acquired by Google. I loved using it but upon the news that it was being acquired I quickly switched back to using my previous email client.

It's unfortunate that great software applications are acquired and then disbanded or boxed away inside the tech giants. I can't comment on the companies and individuals that are acquired in this way though. I would find it hard to say no to any sizeable amount of money for a software product that I owned.
