I find nothing wrong with this advice, so long as you are happy with the L1020 and won't regret it. But, this whole "waiting is stupid... you will just wait for the next rumor" is only good advice if you WANT what is out right now. Otherwise, why would you take it? I have been sitting on an upgrade since late November. There is a phone I like (L920) but is a little long in the tooth and is missing that high def screen I am longing for, and another I like a ton (L1520), just not at the price considering the size is little much for me. So, I wait. No biggie, I will see what is coming, and if I do not think there are better options, I will decide then based on gut feeling which I want.
The L1020 isn't going anywhere. It will be updated to WP 8.1. It will still rock the same amazing camera tech. If you want it, definitely do not talk yourself out of it. Grab it, enjoy it. My daughter owns it, got in December, and feels it is the best thing she owns right now. Just loves it.
BUT.... If you are not in love with it, relax. See what is rumored in the next 2-3 months, and make a decision then.
