Behind the times
"Although cell phones cannot be equated with laptop computers..."
Er, I find it ironic that this statement appears in a judgement that accuses others of being behind the times. Still, at least the legal system isn't as far behind as it was.
I would certainly consider both phones and laptops to be the same kind of device and to judge from their behaviour, Microsoft, Apple, Google and others also regard both as comparable platforms for their software products. They differ in physical size, but are functionally indistinguishable. Both have operating systems, both can make phone calls, both can talk to a variety of other devices and both run applications that you've downloaded from the internet.
