This is the most ridiculous complaint I've ever heard. Greater variety in LEGO bricks? STOP IT NOW! EVERYTHING MUST BE RED 2X4!
I grew up with LEGO and I still regularly purchase, build and play in my late 20s. The new pieces are AWESOME. So are the new colours. Pick a brick and LDD make prototyping, buying and building your own creations a snap (though you have to manually generate a parts list these days). If that ain't enough to keep LEGO fun and interesting, trade in your kid.
Didn't RTFA because WTF.
And yet, I've received complaints from customers buying laptops (not what you'd call sleekbooks or netbooks or ultrabooks or ANY kind of book) that expected it to include an optical drive, which was absent.

Back to the slashmydots' comment though, I think you're missing the mark a little on the demographics that tablets are aimed at. Typing? Printing? USB storage? These were the kinds of things that tablet users already begrudged about their computing experience. And I use my tablet as my PRIMARY web browser. I only browse a "real" browser if I happen to be doing "real" computing on my MacBook.
