Get an iPhone charging dock for $5.99 shipped
Normally $15.99, this handy desktop dock is yours for 6 bucks out the door. It should charge any iPod or iPhone that has a dock connector.
Tired of your iPhone's USB cable flopping all over your desk? Wish your handset could sit upright while it's charging? Sounds like you need a dock. Unfortunately, Apple charges a whopping $49 for its Universal Dock. Surely there's an alternative for cheapskates?
There is! Meritline has an iPhone charging dock for just $5.99, shipping included. (From Hong Kong, no less!) It normally sells for $15.99, already a good deal compared with Apple's product.
Granted, this dock doesn't come with a remote, nor a bunch of dock adapters for charging various iPods. However, although Meritline's product page doesn't specifically mention the Touch, Nano, etc., my semi-educated guess is that this dock will have no problem charging them. (If it can charge a 3G, it should be able to handle anything with a dock connector.)
The dock does have the same kind of line-out port as Apple's, so you can plug in headphones, speakers, etc.
And there you have it! There's not much more to say, other than "I just ordered one." Docks are decidedly handy to have around, and for 6 bucks, how can you go wrong?
