The Mashable team is split on this question. Our resident Kindle expert Samantha Mangino (yours truly) recommends most people opt for the ad-supported version. However, Mashable Tech Editor Timothy Beck Werth recommends paying a little more to get a Kindle without lockscreen ads. Though this increases the price by $20 to $25, you won't be subjected to annoying ads for books every time you lock your e-reader. Instead, you'll see black-and-white photographs of writing implements and other book motifs.

When you're buying a Kindle, you'll notice that Amazon selects the "Lockscreen Ad Supported" version by default. Shoppers must manually select "Without Lockscreen Ads" if they want to remove advertisements from the lock screen. This increases the cost of the base Kindle from $109.99 to $129.99; the Kindle Paperwhite increases from $159.99 to $179.99. For serious readers who hate ads, we think it's worth the added cost.
