Not so sure I agree with at view cultavix - it's a very bad habit to get into, using a FULL admin account to perform your day to day functions, surfing, email, etc...
Your day to day account should not be a FULL admin account! Be it in a domain or just on the local machine, be in the windows world or nix.. From a security standpoint - you should only use the min permissions required to perform the function.. You sure do not need the ability to wipe out any file on the system, or change any file, etc.. etc.. every minute your using the machine.. Running as a FULL admin account gives you this - and leaves the system open to mistakes (deleting something, changing something, etc..) Any exe that you run can run with YOUR permissions, so it would have FULL admin rights (be in on the local machine only - or the whole domain) too..
Do quite a few people do - sure they do, does not mean its a good idea!
