iPhone apps - the 10 smartest and the 10 stupidest

Smart: Kindle for iPhone

They say: "Kindle for iPhone allows Apple iPhone and iPod touch owners to read Kindle books using a simple, easy-to-use interface."

The Reg says: While Stanza (recently bought by Amazon) is arguably a more feature-filled ebook reader, we prefer Kindle because of its effective simplicity and Amazon's recently upgraded and iPhonified Kindle Store, with nearly 300,000 instantly downloadable books.

While you might think that an iPhone or iPod touch's small screen wouldn't offer a satisfactory reading experience, we've found it to be more than satisfactory - and also discovered that having a book-filled iPhone available at all times is a great boredom-banishing convenience.

Stupid: Wooo! Button

They say: "Simple yet guaranteed addicting, Wooo! Button is simply that...a button that belts out an emphatic 'Wooo!'"

The Reg says: Yup, that's all it does. Tap the rather attractive button and your iPhone shouts "Wooo!"

Actually, it's wee bit closer to "Wow!," but does it matter? No.

Wooo! Button is pure, liberating stupidity, and not vaguely creepy stupidity like iGirl - She Obeys or brain-dead stupidity like iPickupLines.

Simple, to the point, and thoroughly pointless.
