I have seen those types of status updates before. It means that UPS has picked up your package, but no routing information has been updated beyond that. Sounds like your unit is being delivered via UPS ground. What is the typical delivery time from your seller to your house? Cross country (Seattle to NYC) could be up to 9 days. If you are really nervous, contact the seller again ... otherwise it should sort itself out in two days or so.
