This service isn't really meant for storing things like your music and video collection, or even your day-to-day chats. I think the analogy of a safe-deposit box at the bank really describes it well. You wouldn't keep your DVD or CD collection at the bank, because storing it would be expensive and your collections are most likely easily replaced. But you might want to keep your wedding pictures, the video of your kid's first step, birth and death certificates, love letters, and important legal documents in a safe deposit box at the bank. You might even store something like your great-grandmother's wedding ring and other historic documents. Essentially all the stuff that would be difficult to replace, and would be worth keeping for the sake of posterity.

Given this, I think 100 GB is probably an acceptable amount of storage for this day and age. That may change in 5 or 10 years time as technologies change and the size of images and videos expand. But in 5 to 10 years time, services like this will probably have changed to keep up with the times.

I couldn't have put it better, thank you!
