I personally think that Dropbox on the PC is great and on an Android phone is complete junk.
Yep, agree ... used to use Dropbox, whilst I have 2 free years of 50Gb (came with the S3), but always found that on the phone it was limited, and that sometimes the videos would not play. Have to say, loving the google features ... so I am gradually moving all my files from dropbox to google, a I paid $1.29 for 100Gb ... not bad
