Make:

@The NYC Toy fair 2008 Franklin showed off their new product, a T-Mobile Sidekick looking device called the "Speaking Spelling Bee" - this isn't a DIY/science kit type thing, but I really liked it and it's a unique gadget (and I haven't seen it anywhere else)... You can play it on the go, or plug in to a TV - awhile back there was a big spelling bee phenomenon, maybe we'll see kids playing this in addition to video games (both are fun)...

Features:

• Multi-player Competition mode (up to 6 players), Game Show mode or improve skills in the practice mode
• Request a definition of the word, origin or to have it used in a sentence
• Compete against friends or select to play against the computer
• High-contrast 2" color LCD display
• Clear speech and sound effects
• Compact design with sliding keyboard
• Connects to most TVs
• SD slot and USB connectivity provides expandability
• The Merriam-Webster Intermediate Dictionary with over 70,000 words, the Merriam-Webster Intermediate Thesaurus and the Merriam-Webster Rhyming Dictionary make this handheld a great companion for school work
  Useful reading timer

Meant for ages 8 & up. It also comes with Sudoku -- I dunno, I might get one, Apple's Mail client seems to miss some of my spelling mistakes - I'd like to fix that with meat skills.
