Microsoft announced today (or maybe sooner, I don't know) that Internet Explorer, Windows long-standing default browser, will be discontinued and not included in Windows 10 by default. According to an article on The Verge, Microsoft will be putting all of their efforts into the yet-to-be-named browser:
We’re now researching what the new brand, or the new name, for our browser should be in Windows 10. We’ll continue to have Internet Explorer, but we’ll also have a new browser called Project Spartan, which is codenamed Project Spartan. We have to name the thing.
So IE will still be available for those who need it (old corprate software and such), but Microsoft will be pushing Spartan instead.
This will surely be welcome news for some. Microsoft has made an attempt in past years to rebrand Internet Explorer, make it faster, etc, but it always seems to fall behind its competitors. Maybe that's why Microsoft is making such a dramatic shift to Project Spartan; because at its core, Internet Explorer is just kind of a crappy browser.
I personally don't think a renamming of Project Spartan is really needed at all. Being a huge fan of the Halo universe, I am in favor of injecting Halo references into other Windows products when possible. Hell, Windows Phone already has Cortana, the personal assistant thing, so it'd make perfect sense to have a Spartan somewhere in the mix.
