On a recent episode of the
Phones Show Chat, I talked briefly with Steve and Tim about my quest for my perfect second device, so I thought I'd add some more detail here. As a bit of background, I have 2 active SIMs - my main one is in my phone (currently a Nexus S) and is an AYCE contract from Three UK. In general, I'll use this as a hotspot for other devices when I need to. My other one is on
GiffGaff. This is a PAYG SIM that can be made to work like a contract if you want it to by using "Goodybags" and/or automatic topups, and uses the O2 network. Most of the time it's in PAYG mode (so costs me nothing when not in use) and I keep it in another phone in my bag, partly for emergencies - if the battery dies on my other phone, or if I can't get Three coverage - and partly to increase my chances of coverage when we're away in the campervan and don't know what to expect on any given campsite. For this purpose when we're going away I add a £10 goodybag that gives me unlimited data for a month (tethering not permitted), plus some inclusive calls and text messages. It occurred to me recently that if this SIM was in a small tablet with an optional decent keyboard, I could effectively have a pretty competent laptop replacement in my bag all the time.
For me, a laptop replacement has to have a decent physical qwerty keyboard good enough to touch type on (so a little thumb keyboard is NOT going to work for me in this scenario, despite its portability) and a screen big enough to view full desktop websites. On the other hand, for media consumption (including ebook reading, podcast viewing/listening, etc.) a small tablet is a better option, as it's lighter and more comfortable to hold for long-ish periods. In terms of form factor, a slightly squarer version of my old beloved Psion5/5mx (i.e. the same width in landscape mode, but a little taller to give a 16:9 display) would be a good size - after all, I did used to carry one around in my bag in the days long before touchscreen PDAs and smartphones, so it clearly passes the handbag compatibility test. The keyboard may have been smaller than even the original eeePC's, but it was absolutely
superb with good feel and travel and a conventional layout, so with my small hands I could use it to touch type completely normally. 7" would probably be the upper limit on size to fit in my bag, and even then, only if it's a slim device with small bezels. In with all the other stuff in my bag, it would need to wear a protective case. A 6" device with good display resolution would probably be the sweet spot for me. Oh, and it'll be running Android so that I can make use of all the apps I've already bought and use regularly.
