...openers, Toshiba this month ships the SD-H400 ($549.99), a progressive-scan DVD player with built-in 80-hour TiVo. Instead of buying two devices, you get two in one. Or you might wait for Pioneer to roll out the first DVD recorder and TiVo combination (DVR-810H, $1,199). The benefit here is that you can greatly expand your memory capacity by burning programs onto DVDs, and make your shows portable--without using VCR Plus+ codes...
Pleased with its performance in still cameras and MP3 players, Panasonic is taking its SD memory card to the brave, relatively new world of digital video. The SVAV100 ($999.95) is the first DVD-quality camcorder to rely solely on flash memory to store footage. The decision allowed Panasonic to drop the bulkier moving parts required to write to DVD or MiniDV cassettes. The result: a full-featured camcorder with a 10x optical zoom and a 2.5in. LCD monitor that really will fit into a pocket of your jeans. Unfortunately, also shrinking is the amount of footage you can store...

With all due respect, I advise her to get out of the house more often. For thousands of years, humans have naturally developed both positive and negative responses to varied stimuli. I hope Heller will revisit her theory and relabel this disorder as a perfectly normal (PN) condition. Mike Randall Oakville...
Heller disagrees, believing her disorder belongs in the canon alongside such conditions as panic attacks and agoraphobia. It does resemble those and other ills--perhaps too much. Her description of an SD sufferer who performs a range of ritualistic chores before bed sounds a lot like someone with obsessive-compulsive disorder. Another, who shrinks from people at parties because she's sensitive to heat and crowds, sounds like a social phobic. Heller argues that such confusion will clear up when psychologists become more familiar with SD...
