Query: Battery life on this thing is a (bad) joke

Do yourself a favor and wait for Dyson to improve the battery life on this thing before you buy one. It only runs on it's battery (you can't plug it into a wall jack for power) and the battery (which requires 3 hours to charge fully) only powers it for 5 minutes! No exaggeration. Cross my heart and hope to die. 5 minutes of vacuuming is all you get, then it's back to the charger for 3 hours until you can use it again. Good God. WHAT were they thinking? I have a full sized Dyson that is without a doubt absolutely worth every dime I paid for it, but this little hand-held is fatally flawed because of it's miserable battery life.
