Unregistered users are limited to one-hour tryout sessions; although they can then run the same software again if they wish, they lose any data or settings from the previous session. Completing a free registration allows users to save their settings for up to four hours over a period of seven days.
The site currently offers three subscription plans, priced between $40 and $70 per month. Each plan offers continuous, persistent access to one or more applications, along with bonuses like multi-user access, extra storage for data files, and uptime commitments.
Click2Try is still in its infancy, as the relatively low number of applications available for tryout indicates. As more developers submit their applications, however, this is a service with genuine potential. The ability to evaluate software, without any up-front setup or configuration hassles, could deliver a huge productivity boost for small businesses with limited IT resources -- and no full-time IT staff.
It's not quite a perfect solution. Such a service will not, for example, give users a good idea of how an application runs on a particular hardware configuration or whether it plays well with other software. But as a tool for performing first-cut software tryouts, the benefits outweigh the drawbacks.
If you business is hunting for open-source software alternatives, keep a close eye on Click2Try. This is definitely an idea whose time has come.
