I would do what is right for me at present, if I'm needing to make a purchase immediately. If I don't need need to purchase a phone just now, then I would wait until either I am forced to or am really wanting to mak the decision.
We do not have the standard data that evaluating purchases required, such as the possible product's price, its guarantee and support level. If I needed something that I didn't currently have, then I would go ahead and make such essential solutions as I need, unless I can make appropriate compromises.
To defer life, on the basis of others' conjecture, is to devalue it.
