I will use it both at home and work:
For home it will server as a browser, email client and for watching sports while the wife watch her shows
The screen would be perfect for that.
At work the possibilities are endless:
Travel - I can ditch the big laptop and use the ipad for presentations (with adapter of course), keeping up with emails, documents (Microsoft Office) and to keep me entertained for those downtimes where you just need to relax.
In the office - Collaboration, whiteboarding, sketching ideas, meeting minutes (need the pencil for sure) and presentations.
