I prefer mixing with vinyl/cds. I enjoy having to beat match my records - there's not really any more thought to it than that for me. There's a lot of skill involved in mixing records well.
As various people have said in this thread it all comes down to whatever you like doing.
If I was just getting into this music now I might not have bought some decks. But I did (back when vinyl was everything) and now I love buying vinyl and having a record collection.
Regarding running a label - well it's true that there's a ridiculous amount of different labels and some of the stuff released is of a very poor standard. But I don't begrudge anyone setting up their own label and having a go if they want to. It's their time and money.
Everyone keeps saying how bad things are in terms of record sales and that techno is on a continually downward spiral, but people shouldn't quit or get disheartened by that. Just keep doing your thing and enjoy it for the sake of it - maybe one day things will start to turn round here in the UK.
