It's going to work fine, my Core 2 Duo laptop serves basic tasks decently, even light PC gaming and Autodesk work.
for horsepower, you should be OK, but my concern would be storage. My primary laptop has 120 GB of storage and I have trouble keeping everything I want onboard. However, much of that is games and fancy stuff like photoshop. An SD card might be something to invest in should you need the extra space.
All RT tablets have free Office onboard (RT, 2, Lumia 2520), so do Bay-Trail tablets I believe. (My Dell Venue 8P came with a free Office H&S/Windows 8.1 combo license. I don't see why not others like the Toshiba Encore, ThinkPad 8... Someone correct me if I'm wrong.)
However my dad's Lenovo IdeaPad Lynx, a Clover-Trail tablet, didn't come with Office, so I used my 2010 license I had on that.
