Microsoft's latest preview version of Windows 10 for phones is here and whether you prefer work or play -- or non-Lumia Windows phones -- it has something new to offer. This is the first one ready to test out the new Universal Office apps (Word, Excel, Powerpoint and OneNote) that are built to run across PCs, phones and tablets alike. Control them via touch, pen, keyboard -- whatever you have they're ready to do business. This access arrives because build 10080 is also the first with a beta version of the new Windows Store. It's a universal app too (notice a theme here?) with a new look, but there are some known issues and the old Store app is still there in case you need to fall back on it. Microsoft announced that it would bring carrier billing for all with the new app and while that's still on the way, it's not enabled yet.
