Indeed. However it wouldnt be a problem if your home broadband upload speed was good. And as the videos are generally large files it wouldnt take long to use up all your cloud storage space... and then customers would have to buy more. Meaning even more money for Samsung.
Not from me though... my home broadband upload speed is only 48KB/s.
I have 3 gb photos but 33gb videos. All backed up to my PC though.
I think I'm going to find some software which will automatically sync and or backup my pics and videos when my phones detects my home network when connected by wifi. Then I can be even more lazy than I already am and not have to use usb.
