I make a subtle distinction between anywhere and anyplace, Jose. My take on this is that anywhere litterally means any geographical location, whereas anyplace means any situated presence. One is measured in miles or kilometres, the other in psychological space - the learning space or coceptual (thinking) space one finds oneself in. Probably deeply philosophical, but it shows me that anywhere is not necessarily always the best time to learn. One must also find the best 'place' - the most opportune and comfortable situation within which to learn.
This sounds fair enough. So maybe we need A4 learning. I think a choice of devices is important. The styles of writing and presentation can be assumed as part of this.
