when traveling i want something small and portable that does not get in the way, especially when backpacking. sure, you could argue that i should leave electronic devices at home and unhook from this dependency to be connected, but that would remove the ability to back up my photos, or write a diary too. there is a case for the responsible use of electronic devices outdoors. and for that i like that device to be as small as is practically useful. a phone is to small because a touchscreen is just not good for typing. it would take me longer, so i would actually spend more time on the device than otherwise.

my first was the transmeta based sony picturebook. since then i have had various other devices of similar size. the largest was probably the OLPC XO. the small but sturdy form means that they pack easily. i just toss it in the bag, not worrying much. with any larger laptop the problem is either weight, or it's so thin that i fear it could break if i don't protect it from things that might push against it.

the small form factor helps to reduce the amount of time i like to spend in front of it. so i really just use it for things i need to do when not at home or in the office.

the downside is that these devices are actually rather expensive, but for me they were what enabled me to be a digital nomad for a several years.
