Not too long, the big draw for products was that customisability. We were provided with empty shells to personalise with stuff we like. Think the iPod, Flickr, Youtube.
Now that the internet has gone into mashup phase, it seems like the next big thing for devices will be hackability. The EEE, Wii, Xbox and a whole slew of other devices have attracted a following of early adopters and other people itching to repurpose the devices for something other than their creators intended and with great success.
What next after hackability? Maybe with new technologies coming out all the time, hackability is something that won’t go away. It will evolve.
