I. Morphology

Folium vitticcii spent every gram it gained on one organ. In outline it is nearly identical to its predecessor: the same aluminium back, the same curved edges, the same single button standing guard on the front face, 241.2 by 185.7 millimetres in each case. An observer holding both specimens at once would find only 1.2 additional millimetres of thickness and 61 extra grams to tell them apart, both spent entirely on the battery required to feed what the front face now contained.

That front face is where the whole argument lives. A display of 2048 by 1536 pixels, four times the count of any Folium before it, at 264 pixels per inch, resolves text with something close to the precision of print, and the gap between a screen and a page, always perceptible before this, narrows to a point where the naturalist is no longer confident which side of the comparison is winning. Apple borrowed the term Retina from Oculiphon retinae, two years its senior, and the claim holds at arm’s length exactly as advertised: the eye simply cannot find the seams.

II. Behavior

The A5X chip inside exists for one purpose only: to keep that many pixels moving at a frame rate the eye will forgive. It does not make the specimen faster at anything else. It makes the screen possible. That stands as the whole of its ambition.

The LTE option is the quieter revolution here. Its predecessors offered 3G, functional but already aging infrastructure; this specimen arrived exactly as LTE networks reached meaningful coverage in major cities, and for the first time a Folium with cellular could serve as a primary connection rather than an emergency fallback. Squeezing the same ten claimed hours out of a battery feeding four times the pixels of the prior generation is a genuine engineering feat, and the specimen runs warm, especially while charging, a fact reviewers noted and forgave without much argument. The warmth was used by Dr. Erasmus Gull, F.Z.S., to declare in print that “a machine with a fever belongs in bed, not on a shelf,” a judgement delivered from a chair he is not known to have left voluntarily since the Society’s last change of premises.^{1The chair itself has its own reputation at the Society, and this naturalist has said everything about it he intends to say in a footnote.} The specimen, unlike its critic, did not have the option of staying seated.

III. Named For

Species in this Archive are, on occasion, named for the person whose relationship with a specimen taught the field what it was for. Folium vitticcii is named for Federico Viticci, founder and editor of MacStories.

In late 2011, Viticci was diagnosed with Stage IV Hodgkin Lymphoma. His MacBook Air was too heavy to carry easily and lacked a cellular connection of its own; this specimen, arriving in March 2012 at the precise moment he was deep in treatment, was light enough to carry anywhere and connected by LTE when hospital WiFi could not be relied upon. Through the months of treatment that followed, moving between hospitals and consultations, he continued to run his publication from it: writing, editing, publishing, and managing a team from a bed, its Retina display sharp enough to make hours of reading and editing bearable.

He would go on to document seven years of using the iPad as his primary computer, longer than he had ever run MacStories from a Mac, in an account titled Beyond the Tablet.^{2Federico Viticci, "[Beyond the Tablet: Seven Years of iPad as My Main Computer](https://www.macstories.net/stories/beyond-the-tablet/)," MacStories, May 2019.} The naturalist records this specimen’s name, as the tradition asks, not as advertisement but as testimony: this is who was here, what they built with it, and why the catalogue remembers.

V. Field Notes

Folium vitticcii was discontinued on 2 November 2012, eight months after its introduction, replaced by a successor carrying a Lightning connector, a faster A6X chip, and a better front camera. The changes were real. The timeline was aggressive. Eight months is the shortest production run anywhere in the Folium lineage. The fact carries no real weight against what the specimen was asked to do and did. The Retina display it introduced became the standard the whole genus was measured against for years afterward, and the LTE connectivity it established became a baseline expectation almost immediately. That is a longer life than eight months, whatever the sales chart says, and Folium vitticcii, Viticci’s leaf, has been in use, in some form, ever since.
