"One of our main goals is to eventually allow people to have their videos anywhere, anytime, on any device," said John Martyniak, Pixorial's senior vice president of products and services, later adding: "A lot of people use Dropbox, or they're starting to use Google Drive. For us to be able to add our service to that, it's a no-brainer."

Pixorial was first out of the gate because Google designated it a "launch partner" for the service. But will other iOS app developers follow? And with cloud-based storage services proliferating--Google Drive is joined by Apple's and Microsoft's in chasing a market that has been dominated until now by services like and --how will developers choose?

Among app developers surveyed by Macworld in recent days, there is wariness.

"I don't think I will be adding any additional cloud services to the app just yet," said Samer Abousalbi, co-founder of , developer of the Dropbox-integrated writing app. "I mostly don't want to chase new drive services every time they come out, because it complicates supporting the app."

Chad Sellers of , which makes the Dropbox-integrated note-taking app, agreed: "As a small dev shop, I don't have the time to support lots of services. I understand the excitement around other services, but I can't justify the time it takes to support them at this time."
