It's the final day of the Luggage-Free challenge, and I've hit Adelaide. This video highlights a common problem I've experienced: a lack of power outlets near the bed.

One of the benefits of travelling without luggage is the sense of liberation it brings. To prove the point, I shot this quick video on the beach at Fremantle, WA.

Working efficiently on a mobile phone is easier if you take advantage of its built-in shortcuts and time savers. These are the options I'm using most often on the Z10.

There are contexts where 4G speed is nice to have, and contexts where it is essential. The Luggage-Free experiment definitely falls into the latter camp.

It's hump day and I've travelled from Melbourne to Brisbane. Working on the road using only a phone means apps are vitally important. Here are the BlackBerry 10 ones I've found most helpful so far, and the handful that have been a hindrance.

While I'm on the road using only a BlackBerry Z10 , the Australian launch date for the Q10, which features a physical keyboard, has been set for 1 July. Check the video for my thoughts on how this might have changed things.

Two days in, I haven't experienced any showstopping issues on the Luggage-Free journey, beyond a mild Wi-Fi shortage in Auckland. But equally I haven't yet developed a working rhythm that makes me think working solely on my phone  would be completely  sustainable in the long term.

My speedy trip to Auckland became even speedier when it turned out my hotel's Wi-Fi was only available in the lobby. Fortunately the Auckland CBD has a few other options.

The obvious  annoyance with going from Australia to New Zealand ? Leaving at lunch and arriving for a late dinner. But that and poor Wi-Fi aside, Day 1 of Luggage-Free is largely  going well.

Efficient business travel means being ruthless, and it turns out I was not quite ruthless enough.  I've realised I can actually take a change of clothes on my week-long armed-only-with-a-phone travel odyssey and still not need a separate bag. This is how.
