If you were wandering the halls of Macworld Expo last week, you might have seen a familiar face -- no, not the everpresent TUAW video crews, but the gadget-loving visage of Richard Thalheimer, founder of The Sharper Image and current head honcho of RichardSolo. The RS booth was a brief walk away from The Sharper Image's floor presence, but I believe maturity prevailed and no miniature helicopters or USB missile launchers were seen to buzz the competition's displays.
The RichardSolo iPhone and iPod extended-life batteries were visible at the show on attendees' iPhones, and most people visiting the booth seemed to be satisfied customers or would-be customers (Steve reviewed the latest model in November). Buyers at the show were eligible for a $30 discount on the original and newer 1800 models, but if you missed that opportunity you can still save: through the end of January, use coupon code 'Macworld' at checkout and get $20 off either product (usually $50US for the lower-capacity model and $70US for the 1800 model).
There's a good list of still-running Macworld Expo discounts at dealmac, but if you know of any that aren't on the list, shout them out.
