I have now installed Office 365 (both on the tablet as well as on the PC) and think it has quite a few nice new features for both Excel / Word and Access. (The main programs that I use)
Now for the real reason why I give it 5 stars:
1TB Cloud and 60 minutes a month Skype! I was in front of it in various other vendors for cloud storage and used Skype, both for work and private. When the cost of storage as well as Skype (Skype Jaja belongs where) withdraws, then the value for money top!
If you need cloud storage and possibly an older Office version uses: =) then get Office 365th
