since you're not looking to get service, an ATT 520 may be a better option since I believe they are cheaper than the T-Mo 521 up front. The only difference is being black and a bit shorter since the 521 is slightly taller than the base 520 model.
Since its powered by Windows, it has Office onboard.
It's worth noting that the Office onboard may not be able to edit old format .xls's. As long as he sticks to .xlsx's, he should be OK.
Windows Phones will function fine without a SIM, you just can't do the phone features, but thats obvious. I've set up and played with my sister's 521 before the Straight Talk SIM she ordered arrived. Worked just fine.
