What's The Deal with Egg-Shaped Gadgets?

Easter Sunday is near, prompting us to highlight the ways technology has finally infiltrated thy hallowed holiday. Jennifer De Leo, over at PC Mag, compiled a slideshow of ten of the oddest egg-shaped tech gadgets to humor us this Easter. I never realized just how may egg-shaped gadgets are out there. I don't know much about product design, but what would elicit gadget designers to create items in such a difficult shape? Is there an actual purpose besides the omission of sharp edges? Anyone?

Some of the gadgets mentioned are actually pretty cool, like the Segatoys HomeStar Pure Home Planetarium, the modPod chair with speakers, and the Grobag thermometer that changes color according to the room temperature. The worst part is, only one of them has anything to do with food. I thought I'd add a few more gadgets to this amusing list:

• Muiro is the robotic iPod dock that plays music from your iTunes library, as it rolls its way around your house. Much like a Roomba, but with streaming music.
  
• Transport is a sleeping pod with speakers, and light-emitting diodes that synchronize to music.
  
• The colorful Egg Bathroom Scale that looks like a carton of eggs, and the Eggulator (a calculator with egg-shaped keys).
