Standards defiance notwithstanding, the web client appears to work as advertised and will surely save many a neck and thumb from premature aging.
It's interesting at this point to think about identity and authentication in WhatsApp. They've never had a username or password and their use of your mobile phone number as your identity seems to have been key to their success (the other factor I'd cite is good cross-platform support).
WhatsApp authn on mobile consists of a once-off SMS verification to confirm you are running WhatsApp on the mobile device hosting the SIM card corresponding to the phone number identity you've claimed for yourself. That said, I recently saw a case of someone using a temporary pre-paid SIM card while she was traveling here in South Africa yet her WhatsApp messages from that phone still appeared to come from her New Zealand number. Not sure how that passed the authn.
The lack of username and password, I believe, is what has led to some of the unnaturalness of the WhatsApp web app. I don't think that their remarks of "the web browser mirrors conversations and messages from your mobile device -- this means all of your messages still live on your phone." reveal all of what guided their design choices. I also doubt that they "don't get the web". Instead I think they need the phone there and online because they have no username and password (or other device-independent authn) and they have thought quite carefully about protecting what got them ahead of the myriads of other perfectly functional IM apps out there in the first place.
