One phone or two?

How many phones do you want - one smartphone that does everything, or separate devices for work and home use?

Personally I'm firmly in the one device camp, I can't back this up with firm data, but my observations at Bristol are that many employer-issued phones languish uncharged, left behind in the office. They are only used occasionally - when someone knows in advance they'll be off-site for a few days. The same people carry a personal mobile with them.

Think of our different users within a university:

• I reckon that most academics want one device. The traditional of the academic for whom work is their vocation plays into this - work & personal life merge.
• Our students certainly only have one device (we don't pay for their phones!).
• Our estates staff (electricians etc) have particular requirements and definitely need a work phone as they are out on call around the campus.
• Our academic-related staff: this is where there is the greatest divide into the two camps. Some people are strongly of the opinion that they want two phones to keep work and home separate, others want one phone and somehow manage to juggle their identities.

Is this a divide between the Digital Natives and Digital Immigrants (of whatever age?).

Leaving aside who owns the devices, I'd like an approach with at least two prongs, as per Gartner's Managed Diversity Strategy:

1. Provide basic low-level support for all devices. For example, we have step by step instructions on how to access our email and Calendar on all major phone platforms.
2. Provide comprehensive support for one specific platform (eg phone preconfigured before you get it, help desk support, perhaps custom applications).

I want to do both, but in the current economic climate option 1 looks attractive while 2 is difficult to justify.
