juiceme has already said it but the problem with this comparison is that you're comparing a jailbroken device with a stock device.

As soon as you jailbreak an iPhone, bang goes your warranty, OS updates and certainty of what works today will work tomorrow.

One of the things which pisses me off with even jailbroken iOS devices, and perhaps this is no longer the case with the right jailbreak tool and a patched kernel, is iOS's task scheduler will close tasks down if put in the background after 10 minutes. It's not unusual for me to have a website open reading docs and an ssh terminal working. On iOS you have to remember to keep switching between Safari and ssh (I use Panic's excellent Prompt app). I rarely bump into that problem on a Nexus 7 with stock Android and NEVER on an N900 or Jolla.

Why would I void warranty when I don't have to on other platforms; platforms that are much cheaper too.
