Techradar published a review on Office 2013 Technical Preview

Do you feel modern? The next version of Microsoft Office gets the Metro treatment, with a touch-friendly interface as well as new features, and goes to the cloud, with subscription pricing, on-demand installation and automatic syncing of settings and documents you save in the cloud ? if you want to pay for it that way. So we've taken an in-depth look at what you get and how well the Windows 8-influenced interface works in practice.Although the preview is called Office 15, individual applications like Word and Excel get the 2013 tag, so we expect the final release will be called Office 2013. As usual, the technical preview includes more applications and features than you'll get in all the versions of Office 2013: Word, Excel, Outlook, PowerPoint, OneNote, Access, Publisher, InfoPath and Lync - plus the Metro versions of OneNote and Lync.
