How to replace a broken front panel on your iPad

If you crack the front panel on your iPad, you can either live with it, buy a new one, or fix it.

For those with an AppleCare+ or other warranty that covers accidental damage, the choice is obvious. Get the unit fixed or replaced. If your iPad isn't under warranty, you don't want to buy a new one, and you're ready to tackle a challenging, but satisfying do-it-yourself fix, here's a guide for replacing the front panel.

Before you tackle this fix, I encourage you to watch my video on what to know before trying to fix a smartphone or tablet. more

Why an iPod Touch costs more than the sum of its parts?

We've all read those blogs that "reveal" the parts cost of a fill-in-the-blank, Kindle, iPod, or Palm Pre. If you ask me, this simplistic, by-the-numbers gambit overlooks most of the costs of bringing a product to market.

First and foremost, products, all products, are priced to what the market will pay. I don't care if it's a 16-ounce bottle of Poland Spring water, Coldplay concert tickets, or a Ferrari 599 GTB Fiorano, retail prices are determined by what the market will pay. And luxury products have higher profit margins than mass market stuff. Oh really?

But the mindless rash of blogs that purport to add up the parts costs, for example $39.51 for the display, $15.96 for 8 gigabytes of flash memory, $15.41 for components, and $12.39 for the 3-megapixel camera, to calculate the cost of anything are hugely misleading. The writer merely subtracts the parts cost from the retail price and concludes the difference is the "profit."

Does the writer assume the company's factory doesn't pay rent or for electricity or heating and air conditioning? And that the factory labor force works for free?

These articles completely ignore other costs, such as research and development and engineering expenses associated with creating say, a Kindle. Manufacturers also pay significant licensing fees for technology used in their products.

Shipping costs of large products such as flat-screen TVs must be factored in before determining the final cost to the consumer.

Oh, and what about the online or brick and mortar retailer? They have their own set of expenses for rent and employees. Some of whom might need health insurance.
