Charge time is getting to be less of an issue, although it really isn't that big a deal to start with, To put a different perspective on things, would you rather travel to a service station once a week to put petrol in you're mobile phone to run it, queing for the pump, queing to pay, or would you rather just plug it in to charge each night?
Also running cost is becoming a rather large consideration, current EV drivers in the States calculate that the total running costs of their vehicle INCLUDING the neccessary periodic replacement of the batteries equates to about 20cents US per litre for petrol at prices current a year or so ago.
As for cumbersome due to the weight, The purpose built EV's (as opposed to a converted car) are amazingly agile and very quick around corners due to the weight of the batteries and their position (resulting in a much lower centre of gravity than standard vehicles) Footage of these EV's going through handling testing shows much less body roll at high cornering speeds than standard vehicles
