who would use a smartphone and tell people it's their main pc? that's frekin' craaazy right there
they might be pretty nifty personal entertainment and information tools, but
for me if it doesn't have the following, it isnt a pc:
1,
usb, mini usb, ps/2 or some other popular form of peripheral attachment port
for high speed input/output such as audio input, printer / webcam outputs or
precision controls ( any game peripheral or graphical tablet, mice ect.)
2,
a reasonable definition display to view created media, games, tv
( at-least 360p, because that's youtube minimum and if you cant watch youtube on your pc it's a joke. )
( as in, no mp3 players, radios, watches, cameras, whatever that happens to have a usb port on it )
3,
the ability to run an operating system of reasonable quality
and no, i do not mean 'windows 7' i mean any third party os that will run media content, games, word processing, ect.
( no Chinese backstreet operating systems, or devices that only run java, hell most people's car sat-navs can run java. )
android or equivalent certainly qualifies.
4,
a computer must have a replaceable battery if it has one, and hard-drive swap-ability
personal preference on this one, basically anything that has built in battery's or non serviceable parts such as mp3 players with wifi and you-tube and stuff, do not count as pc's ( creative make one with this kind of spec list, crazy as it sounds )
( [sarcasm] oh, and macs, because macs are not pc's either and as nobody will bother reading this who cares anyway. [/sarcasm]* )
5,
Software
your device must be able to run software of some kind, 'apps' count but only if they are capable of processing tasks such as word processing, medis content creation, modification or audio processing and modification
6,
if you have a smartphone that can legitimately do everything i listed, congrats it IS a pc by any reasonable definition but for most people i honestly doubt that's the case.
honestly, i think a tablet with wifi and atleast a usb port with android or windows 7 or equivalent is the minimum level for something you can call a 'pc' they at-least have the ability to attach a keyboard, and all the peripheral goodness you could want / need ( depending on brands ) and you can view / run pretty-much anything.
else where is the line between 'pc' and calculator?
( which by definition is a personal electronic device that performs useful calculations, and outputs them in a user friendly way ) = pc.
if you are so vague about what a pc is, you could claim most mp3/radio devices are pc's, watches are pc's as they compute a task and output a result
