Surprisingly, plenty comments in this thread actually tell otherwise -- and keep in mind those users are already used to cryptocurrency clients and far from clueless. They already know the gist of the software. BUT, example:

It is not as smooth/simple as you make it appear to be.
To succeed in some serious adoption user convenience must be #1 priority. Don't expect anyone to fiddle around or learn. You know, it all seems simple if you know what it is. Sure, it's extremely simple for me. I understand the software. "Average guy/gal" doesn't, cause he/she neither has the time nor interest to get into this.

If you really want to see average people (including those who reject Bitcoin) use this thing, the suggested electrum-style wallets / web wallets etc. -- everything that makes it as simple to use as PayPal -- are absolutely, fundamentally essential. A realist clearly knows that if one ignores potential user's convenience, users will ignore NEM. It is as simple as that. If it's not easy to adopt it won't be used. But I guess we're all aware of that, right?

just my 2 cents.
