I have a number of apps on my desktop that do not come from the washtowel, and are not loaded with malware. I have the Amazon Music app and the Weatherbug app. I use the music app to buy my music (including sun-worship songs). So they want to make me listen to Kingdumb maladies instead of Led Zeppelin? Or to not be able to find out what the weather is going to be for the next few days? Does the washtowel have any approved weather apps that have reasonable accuracy?
Not to mention, there are plenty of apps for mobile devices (of which I do not have, because they cost too much money for service charges). Yes, you do need to be selective on which apps you install, but because your device has limited memory and having too many garbage apps will slow down your device or make it unstable. By all means get whatever useful apps you wish for your device, with this caution in mind. The washtowel app is probably the worst offender of being a waste of memory for your mobile device, and probably the worst in terms of compatibility and stability issues.
