If you aren't going til the end of april, I would at least wait March. If by the last Tuesday in March we don't see new models then buy. Even if you don't need the new technology (whatever that may be) you will be kicking yourself if you buy one and then the new ones come out.
Well "could suffice" would basically be suffering as it has trouble performing some of the daily functions. But the difference from suffering for two more months could be worth it.
