While it would certainly be nice to have the option, I think that the webwallet would be much more convenient for the average user since they will have access to their wallet from any device connected to the internet, versus that one computer. A lot of people I've talked with dislike have to store the entire blockchain on their computer and worry about having to keep everything synced, the webwallet solves this problem and appeals to new users for this reason.
Agreed, but what happens if the web wallet is offline for some reason? I think that it is also disadvantage to count on others about your personal security. I would prefer having the wallet and count to myself. And like you said.. it will be nice to have that option, but idk if it's hard to implement it.
True that is a valid point. While a full featured version of the webwallet (one with decentralized exchange in place, creation of assets, notary, etc.) may be more time consuming to implement, a stripped down version with only the ability to just view/send assets should be much easier to implement.
