Do you think it buying a console at launch is good or bad

[Cobretti2]

All depends which console you are buying:

Micrososft = no as RROD on launch models.
Sony = maybe as can have issues but usually because of being dead on arrival and not dying a week or two later.
Nintendo = yes as you will be very unlucky for nintendo hardware to fail early.

However I expect microsoft and sony to mature eventually and be up to standard day one.

By all rights PS4 being Sony's 4th console should be almost perfectly made at launch.

Next xbox could go either way, but I think Micrososft have learnt from their mistakes in the past.
