How Many Go Into One?

How many multi-tasking functions and features can be crammed into one device? Can math help?

While researching this subject, I found the

• Three-in-One Pen Tool (Adobe Illustrator)
• Fidelity Four-in-One Index Fund
• Five-in-One painter's tool
• Six-in-One wire stripper tool
• TrueTemper Seven-in-One planter's buddy garden multi-tool
• Eight-in-One fingernail manicure set (sure to be taken by security in the airport)
• Nine-in-One calculator, box cutter, memo pad, laser pointer, and so on
• Ten-in-One Circus sideshow with freak shows, wild animals, etc. 
• Eleven-in-One Spinal Tap Volume Control (I made that up, just to see if you were paying attention.)
• Twelve-in-One Web Page, where the owners created 12 films in one semester of school

I tried to find a thirteen-in-one device, but only came up with this passage: In each of the planes of existence, the thirteen in one, the mystical number ... shall direct the unfoldment of being.  Uh, hmmm. Well. We'll cut this off and get back to the subject at hand.

Is there any limit to the number of items in one? I suppose not. But a multi-function device is limited in its utility if and when when the functions overwhelm the user. More is not always better.  Here's my candidate for king - the 80-in-one memory card reader.

In theory, this reader can replace a separate reader device for each of the following memory cards:

• CF I/ CF II / EXTREME III CF/ EXTREME CF/ ULTRA II CF/ HS CF/ XS-XS CF/ CF ELITE PRO/ CF PRO/ CF PRO II
• IBM MD/ HITACHI MD/ MAGIC STORE
• MS/ MS PRO/ MS DUO/ MS PRO DUO/ MS MG PRO MS MG/ MS MG DUO/ MS MG PRO DUO/ EXTREME MS PRO/ MS SELECT EXTREME III MS PRO/ ULTRA II MS PRO/ HS MS MG PRO/ HS MS MG PRO DUO/ HS MS PRO/ HS MS PRO DUO/ MS ROM
• SD/ MINI SD/ HS MINI SD/ EXTREME SD/ EXTREME III SD/ ULTRA SPEED SD/ SD PRO/ SD ELITE PRO/ HS SD/ Micro SD
• MMC/ MMC 4.0/ HS MMC/ HS RS MMC/ RS MMC/ RS MMC 4.0/ MMC Mobile
• SIM (mobile phone) Card 

Whew!

Do you think there are really 80 different kinds of memory cards? Who verifies these claims?

That's the champ for now, I guess, unless you grant me a bit of poetic license:
Could it be Disney's One-Hundred-in-One Dalmations?

PS - Yes, I know it's really One Hundred and One Dalmations!
