While the Amazon Appstore may have its downfalls, it also has its upsides -- namely good deals and free apps. Thus is the case with its new promotion called "Geek Week," in which some very useful apps designed for hardcore Android enthusiasts have received a nice price drop.

As for the apps in question, you'll find some well-known tools and utilities in the mix:

Easy Tether for $4.99 (normally $9.99)

Root Explorer for $0.99 (normally $3.99)

WidgetLocker for $0.99 (normally $1.99)

Wave Launcher for $0.99 (normally $1.99)

SetCPU for $0.99 (normally $2)

RepliGo Reader for $1.99 (normally $4.99)

Xtralogic Remote Desktop Client for $12.99 (normally $24.95)

BackupEverything for $0.99 (normally $1.99)

Among those, I highly recommend Root Explorer and SetCPU (for overclocked devices), but the majority of those apps are definitely worth the sale price.

So, if you don't already have it, there's no better time to grab the Amazon Appstore and take advantage of a good deal on some must-have apps.
