Challenge is, I travel weekly. So unless I want to have access only to personal data on Saturdays (I can tell you, doing bills and taxes on your one day home is no way to make friends), I need to travel with personal data accessible. And I have a work-issued and -maintained laptop, so I don't feel comfortable storing it there. I guess one option would be to have a home PC with the data backed into the cloud and only access it via the cloud, but I'd rather have a drive I carry with me that's safe and will self-destruct within five seconds if teh wrong people snag it.
