I have it in front of me and confirm that the RT does have a desktop environment with office, and if you hit window+r some other programs, like cmd, and powershell.
Don't be deceived. 10$ an hour on freelancer.com may seem like the norm, and you may well take some jobs that end up paying about that, but:
1. Not all skill areas pay that poorly. Look for an underserved area and exploit it.
2. Those low paying initial projects can turn into long term good paying clientele. I did exactly that with six iOS projects in 2011. The effective hourly rate on the initial jobs was 20-30, but once I had proved myself to the client, I would quote at 80-90 an hour, with no objections.
3. You're a student who can't take a fulltime job. In that situation 10$ an hour work from home isn't a bad deal.
