Education has many goals and one of them is to teach them spelling. The fact that fourth grade homework is spelled correctly does not matter at all - the goal is not to produce correctly spelled homework.
Regardless, why be stuck in the past with things like handwriting or spelling or cursive?
It's also not clear to me that spellcheck will lead to people forgetting how to spell, since it's all about notifying you of spelling mistakes.
Whiteboards are something I use more often at work these days, but not really when I was in school.
It's utterly bizarre to me that people in this thread are seriously suggesting that spelling is an obsolete skill.
