All the features you mention above are helpful and worth every penny. These are all useful techs, it all depends on IF you can spend the money, if you can, go for it, you will enjoy all of them, if you cant, don't worry, you will never miss them.

It's more a personal valuation question to users than technical. I already have the features and specs.
