Internet space is becoming more and more important, not only the fun in sharing your photos with your friend, but also in the confidence that you can work anywhere of the world and anytime you choose to.

I used to pay $100 for 20GB using apple MobileMe, no offense of the price, but I have a better plan here. Check out Dropbox where they offer you 2GB for free instantly when you sign up. The software lets it merge with your operation system and be one of the folder. And you get a nice notifier monitoring the usage of this folder as well.

[updates] The sync feature is well implemented, whenever you put file in dropbox folder, it enters an query to be uploaded to the server, and the icon indicates if the file is updating. And when the server gets the updated file, it’ll notify all connected computer to update them into latest version. The drawback you can see from here is that all computers has a copy of all files in your local hard drive. And if you just want to transfer a file from this machine to another one, it’s better to do a direct ssh if available.

As for the charge, they let you to refer to your friends to earn extra free space, after you fills up all referrer program, you can have up to 5.2GB free storage space to play with. And if you really like their service and want to extend it, they offer $100 for 50GB as a start. Very attractive IMHO.

[more updates] Dropbox raised the referrer program to 10.2GB Max free space, which is really nice. And I found out they keep track of the files version, so if you want to go back to old version of any single file you overwrote before, just follow this help tip.
