re: iPad killer
Ah, the old 'WoW killer' POV re-hashed.
I respectfully disagree:
1. another new entry in a *very* competitive space
2. MS Office isn't the killer app for tablets (could be a play for the business sphere - my previous company was handing out iPads for front-line staff, despite all 10 kinds of merry hell IT encountered trying to set group policies across the assets)
3. it's less about the OS and more about the eco-system
This is where Apple has achieved lock-in. Thankfully, the iPad isn't as tied to iTunes (although the chain is still there - and yes, it is a PITA) as it once was, and while iOS 7 is a lil Fisher Price 'My first tablet' in terms of garish colour scheme, it is an improvement (as well as helps to sell more iDevices for Apple). It's the App Store that is the *real* killer app.
For all the fart app jokes, there is a wealth of quality apps that in tandem with the actual iPad experience, actually causes me to insert the Charlton Heston quip, "I'll give you my iPad when you pry (or take) it from my cold, dead hands". Or, more realistically, when Apple decide that it's time for an upgrade re: forced obsolescence.
I do concede that the increased battery usage (if holds up in real world usage) is a welcome feature. Not enough for me to put aside my iPad. Note: I have no qualms with handing over my HTC Desire - battery usage is f**king appalling!
