jcasman passes along a heads-up on Lunascape, a Japanese browser company that is releasing its first English version of its Lunascape 5 triple-engine browser. It's for XP and Vista only. There are reviews up at CNET, OStatic (quoted below), and Lifehacker. Both the reviews and comments point out that, in its current alpha state, the browser is buggy and not very fast; but it might be one to watch. "How many web browsers do you run? If you're like me, you regularly use Firefox, Internet Explorer, Chrome and Safari. Each of those browsers, of course, has its own underlying rendering engine: Gecko (in Firefox), Trident (in Internet Explorer), and Webkit (in Chrome and Safari). Today, a Japanese startup called Lunascape has released an alpha version of its Lunascape browser ... that allows you to switch between all three of these prominent rendering engines. The company says that the Japanese version of Lunascape has been downloaded 10 million times and touts it as the fastest browser available."
