Apple's Watch is now on pre-order at Apple's Store, but unlike Katy Perry, you're going to have to wait until at least April 24th to get one. It could take a lot longer than that if you don't order one sooner than later, however, and if time is of the essence, you may have to settle for a model you didn't have your heart set on. Apple said that it expects "strong customer demand will exceed our supply at launch," and information on the Apple Store backs that up. For instance, the 38mm sport model is shipping between April 24th and May 8th, but the 42mm model isn't going out until May 8th at the earliest.
Nevertheless, some folks are reporting that the ordering process was smooth, and if you're so inclined, you can grab up to two of them. If you choose to go ahead and not buy a $350-plus fashion item sight-unseen (£299 in the UK), you can head to an Apple Store, even though you won't be able to order it there. Should you go that route, however, Apple recommends using its concierge service to book an appointment. Another option to try one out is to visit three department store pop-up shops in Tokyo, London and Paris.
If you're more interested in a new laptop than a watch, the retina-screened MacBook is also up for grabs. There's no issues about buying that model, which is showing ship times of 1-3 days. The only downside? The price for that lack of weight and retina screen is a princely $1,299 - $1,599, or £1,049 - £1,299 in the UK.
Update: The shipping date for the cheapest 38mm Watch Sport is now showing as "June," though more expensive models are available sooner. As there's now less point in rushing, you could even go to an Apple Store and, say, try one on.
