Popularity
IrDA was popular on PDA's, laptops and some desktops during the late 90s through the early 2000s. However, it has been displaced by other wireless technologies such as WiFi and Bluetooth, favored because they don't need a direct line of sight, and can therefore support hardware such as mice and keyboards. It is still used in some environments where interference makes radio-based wireless technologies unusable. IrDA popularity is making a comeback with its highly efficient IrSimple protocols by providing sub 1 second transfers of pictures between cell phones, printers, and display devices. IrDA hardware is still less expensive and doesn't share the same security problems encountered with wireless technologies such as Bluetooth. In addition, some Pentax DSLRs (K-x, K-r) use IRsimple for image transfer and gaming.

Famous quotes containing the word popularity:
“A large part of the popularity and persuasiveness of psychology comes from its being a sublimated spiritualism: a secular, ostensibly scientific way of affirming the primacy of “spirit” over matter.”
—Susan Sontag (b. 1933)
“There are few cases in which mere popularity should be considered a proper test of merit; but the case of song-writing is, I think, one of the few.”
—Edgar Allan Poe (1809–1845)
“The popularity of disaster movies ... expresses a collective perception of a world threatened by irresistible and unforeseen forces which nevertheless are thwarted at the last moment. Their thinly veiled symbolic meaning might be translated thus: We are innocent of wrongdoing. We are attacked by unforeseeable forces come to harm us. We are, thus, innocent even of negligence. Though those forces are insuperable, chance will come to our aid and we shall emerge victorious.”
—David Mamet (b. 1947)
