Good to see coverage, but a few notes:
Few points to note and correct, I'll start at the top:
1: The vapour is not water vapour, it's VG/PG vapour.
2: The term most often used during discussion is "harm reduction" rather than minimisation, but that's a little pedantic.
3: eGo actually refers to the battery form factor, the thicker battery used in the article is one, but eGo-T is the name for a now obsolete kit which included an atomiser with a removable plastic capsule-like tank, usually a semi-transparent frosted tank with a moulded mouthpiece integrated into the end. I can understand this mistake because the batteries are often still branded as eGo-T, but for the sake of completeness I thought it noteworthy. The top half of the eGo-T kit in this case appears to be a Vision eGo (also known as a Stardust in the USA).
4: The kit which looks like an immitation cigarette (#2) is neither eGo nor eGo-T, this is known as a "cigalike". The battery itself appears to be an automatic 510 battery, and the filter-coloured piece with the liquid in is called a cartomiser, a 510 cartomiser (to match the threading on the 510 battery). As this uses a cartomiser (a "cartridge with a built in atomiser", as opposed to the earlier types where the two were separate pieces), it isn't a "-T", as the -T stands for Tank. Unlike a tank, a cartomiser is filled with a wadding which absorbs the liquid to store it.
5: Device #3 is also misnamed, depending on how you look at it. 510 is several things, it's the name for the thread type which connects an atomiser to a battery (specifically the thin type, the type which is on the end of that cigarette sized ecig's filter end), but it's also used to describe the size and shape of battery included in kit #2. However, kit #3 wouldn't really be considered a 510 kit, since it uses an eGo battery with what's called eGo threading - that is, whilst it's compatible with 510 threading atomisers, it also has an external thread which accommodates aesthetic improvements and larger atomisers, like tanks which are threaded on the widest part of the base, not the centre. Also, there is no foam in the type of "clearomiser" (clear cartomiser - usually has a transparent tank and no filler wadding) used here, just a set of silica wicks leading to the atomiser coil.
6: #4 is in fact a Kanger (the manufacturer) ProTank, not "Kanga".
7: A "mod" is usually the term for the battery tube, with or without electronics inside it. Pretty much anything larger or more complex than an eGo battery could be considered a mod. Without electronic is called a "mechanical mod", it relies purely on a mechanical switch to connect the battery when you want to use it, and has no regulation or safety circuitry. With electronics is an electronic mod, and it usually contains regulation circuitry, safety protection and often has functions for increasing and decreasing the amount of power delivered to the atomiser coil (which is known as Variable Voltage or Variable Wattage). Although a tank could be considered a mod, it's not a common usage of the term. Of course, the term itself refers to a time during which people would "mod" their own ecigs, by modifying existing ecigs or creating their own custom ecig power supplies out of flashlights and the like.
8: Flavours are, as the article suggests, entirely subjective, but tobacco flavours very rarely taste anything like you expect them to taste. They generally don't taste how you remember a real cigarette to taste, so don't expect an absolute replica of the experience of smoking a cigarette. On the plus side, there are thousands of flavours, and there's bound to be something you like amongst them, pick a few and see what you like, it's a process of experimentation.
Source: Me, I've been vaping exclusively for 3+ years and I'm involved in ecig communities.
Having said all that, I'm very glad to see coverage of ecigs on ElReg, and I can't recommend ecigs highly enough, I have a handful of large mods (a VAMO, a Joyetech eVic and an Innokin iTaste MVP in case anyone's interested, with iClear 30s and a ProTank 2 on top, plus various other bits and bobs for emergencies) and I love vaping.
