Virtualization now cross platform
Adobe has taken application virtualization one step further than Softgrid/Thinstall, now you can use the web aware Adobe Air applications on any compatible platform (basically any web-able os).
Its an interesting idea that surely will appeal to many web-service providers.
Another free WinZip replacement (supports many formats incl RAR), have not tested it yet but it looks promising.
A different solution for online backup is to use Jungle Disk. Jungle Disk is a software that utilize the Amazon S3 storage network which is very fair priced (approx $0.18 pr GB a month + an upload fee of about the same).
The solution has a quite good agent software (also comes in a USB version, so you can carry your online disk) which allow for scheduled backups, bandwidth throttling etc. etc. and the security seem quite convincing.
In the near future I will be comparing this with the www.Keepit.com solution, my feel for now is that Keepit is more home user aimed and Jungle Disk is usable for both, however the low FIXED price for Keepit do seem tempting.
