How google drive defeat dropbox?

Google drive have been out this week. Google gives all of users 5gb storage freely.

In size of storage, It is useful compared with dropbox, suger sync and sky drive.

However, I think leader have a big advantage about this market. Because, user emphasize cooperation with other application rather than bigger space.

For example, "I bunko HD" is one of the most popular application in ipad. this application have a function that be able to download from dropbox. If I don't use this from Google Drive, I am NOT going to use it as main cloud storage.

Most important thing is that Google should promote collaboration of other application.

Foreign people don't wanna smaller laptop or tablet

If you see both sales ranking of amazon.com and co.jp, you can find each tendency:
In japan, netbook or other smaller laptop is popular. on the other hand, Bigger and
high-class laptops are popular in America.
 I believe that popularity of netbook is grobal phenomenon. But result is different.
Perhaps, In America main transportation is car: easy to bring even if it is a little heavy, but Japanese main transportation is train : congested, crowded, and no one
wanna bring heavier one!
