Despite a lot of skepticism here,

the entire periodical publishing industry will change because of the arrival of tablet computers from not only Apple, but likely Windows 7-based tablet computers from Asus, Dell, MSI, Toshiba, etc. and possibly a tablet computer running a touchscreen-aware version of Chrome OS.
(We should note that Windows 7's touchscreen support makes it very viable as an OS for a tablet computer. Based on what I've seen of Chrome OS, it appears Google may also add full touchscreen support along the way, too.)
2-3 years from now, tablet computers with very power-efficient Organic LED displays (which no longer need power-hungry backlighting LCD panels need today) may finally become reasonably priced. At that point, such a tablet computer will act not only as a portable computer (with optional keyboard) and also as a high-quality text reader at the same time. This opens the door for
HIGHLY interactive digital periodical publications like that demo Time, Inc. recently showed based on
Sports Illustrated magazine. Freed from the "dead tree" limitations of how many pages per issue, we could end up with longer articles, a lot more "sidebar" articles, and definitely a lot more pictures per article, too.
In the comics industry, it also means a lot faster delivery of the latest comics. Much of Scott McCloud's vision of the future of comics from his book
Reinventing Comics now becomes a reality, especially given the enormous computing power of today's iMacs and Mac Pros. Indeed, we are starting to see this in Japanese manga, where Rumiko Takahashi's current series
Kyoukai no Rin-ne is being published in Japan in Shogakukan's
Shounen Sunday anthology and Viz Media's own web site in English-translated form on what amounts to almost the same publication date for each new episode!
Even the newspaper industry must embrace this new technology. I can see within two years Gannett's
USA Today in a digital daily edition with highly interactive content far beyond their current digital daily edition (which currently is essentially a digitally-scanned version of the "static" published newspaper itself which is available 5:30 am Eastern time every weekday).
In short, the
mainstream media realizes that they have to be relevant and must embrace digital distribution as they place less emphasis on "dead tree" distribution. With the plethora of tablet computers and laptops with full touchscreen functionality arriving over the next 2-3 years, the change will start to happen full-force.
