The main factor in security, is the diligence of the user. I would bet that a vast majority of people that have "malware" attacks via their device, have inadvertently allowed questionable software
by not paying attention to certain signals (horrible reviews
, questionable permissions, etc). The report does mention that a lot of instances are also Premium SMS variants. Most of my experiences with those, while annoying, can be stopped via simple means. There are also mobile security options for Android, and I imagine iOS as well.
As for the rest though, I imagine both are comparable in apps. I've toyed with a few on my G2, and they seem reasonable. iOS does have a pertty hefty developer base, and I'm sure there are some really exceptional options for it, and usually sooner than a Droid release (I've seen that a lot, devs will get the iOS out first, and Droid 2nd).
iOS is a very stable platform. It's a nice advantage they enjoy, since they don't have multiple manufacturers changing things around. It's very user friendly for new users to smartphones/tablets. You lose some customization and personalizing that android offers, but that's also depending on what you look for. But you also have a lot more options in regards to phones, features, sizes, and whatnot when you go android. I personally don't like Apple myself, but that's a personal opinion of mine, and it's based on the company, not the products. But I have also had Android phones for going on 5 years now, never a single
issue with them (I don't go "cheap" with the models, I always stay at least upper-mid range, though lately, it's been the upper models at release (Thunderbolt, Galaxy Nexus, and now the LG G2 - amazing phone
, btw). That will also be something to remember: The "cheaper" the phone
, the less satisfied you will be with the experience.
Another thing, is if you currently have either currently? Sometimes it's easier to stay with one over the other, if you already have it.
