Cant reply directly to wand3r for some reason. Re his comment spacex could engineer something that wouldn't leak or need instant refuelling - I wouldn't be surprised if they could - but they have around 30 years of advancements to help them!
My 4 year old Samsung received an update to 7.0 last month, and a security patch the week after. I agree android patching is poor compared to apple, but a lot of fault lies with the phone companies refusing to pass updates onto the end user rather then the company making the phone.
