Features Set:  

While SpaceTime provides all the essential features of an Internet browser, they stop there. SpaceTime lacks a password manager, RSS feeds, parental controls, or add-ons. And with this much emphasis on multiple tabs, SpaceTime seriously needs a save tabs function.

Ease of Use:  

SpaceTime is pretty easy to use, but not as intuitive as other browsers. The interface is neat, but not simple enough to use.

Security:  

While SpaceTime does allow you to quickly and easily delete your browsing history, it doesn't have solid security. There is no anti-phishing technology or pop-up blocking.

Speed & Compatibility:  

SpaceTime is compatible with most sites. The Internet browser struggles with speed, though not as much as one might expect. See how SpaceTime compares with other browsers in a head-to-head speed race.

Help/Support:  

SpaceTime's help is useful but maybe not enough for such a complicated browser. They have a user guide and user forum, but we would really like to see some tutorials and online help.

SpaceTime is pure Internet browser eye candy, but sacrifices features and speed. Still, it doesn't feel gimmicky. We recommend you check it out; SpaceTime is fun to see but probably not to use long term. SpaceTime is a good start to a really impressive concept, but it needs more. For more features and an easier to use browser, we recommend Firefox or Google Chrome.
