Well, sure hope that you are also getting your spouse other gifts as well — romantic ones, sentimental ones, etc.!!
And, are getting separate gifts for each of those occasions — not simply the Mac as an all-in-one gift.
For example, a memory scrapbook of photos of you all as a couple, a candlelight supper that you prepare, a book series your spouse is interested in, rom-com DVDs, several things that fit your spouse's favorite hobby, gift cards for household chores your spouse does but that you will now do, and so on.
Spread out the celebrations, too, so that each even is special, and honored separately. Your spouse deserves that and it will extend the fun and celebrations over more time!
But a MacBook?
