Don't know how this will affect altcoins, specifically ETH mining but Videocardz has a post up about 1080 specs and it breaks down Bitcoin mining vs 980TI and R9 Fury X.

1080 - 1056.438 mHash
980ti - 769.191 mHash
R9 Fury X - 857.575 mHash

If that scales, in theory the 1070 for $380 might beat the R9 Fury X in the above instance.

at some point you have enough coins and then you can just sit back and enjoy seeing the value of your coins go up. i am doing the same right now. the only reason i buy currently is because i am a trader. this allows me to generate some extra coins while i am holding my other coins safely in offline storage.

Too late mate, George Osborne's already bought Dodgy Dave some bitcoin so he can buy some flake off Nucleus.

Although I don't own any ETH yet I think in this year it will become more "stable" regarding prices - just like currently BTC is (but let's see what halving will bring)

I used to buy some small amounts when the price has fallen more than the regular small movements, sometimes the price fall more but sometimes the price recover so I consider it a good type of trading in my opinion.

I think the price will not go down again, unless the Bitcoin Core team rejects the ultimatum issued by the miner and payment processors.

When I need and when prices fall 

I Bitcoin bought for a low price. I was lucky. So I hope it's going to rise so I've profit.
But perhaps you can now buy and you may still have profit.

Yeah sounds like a lot of hassle, think i will just continue to use a blockexplorer website.  

it would be nice  although if it went back up to 1000, more "bitcoin inventors" might be raided it seems. bit sad really
