Susie Ochs, Executive Editor for Macworld, gives her take on life with an Apple Watch. In her case, there’s plenty to like, but this is from the Things I hate about it section:

That brings me to my main complaint with the Apple Watch: Its poky performance. Since the lion’s share of the data it presents comes from your iPhone, be prepared for lags. Even scrolling around its face, the refresh rate seems a little laggy compared to what I’m used to (and spoiled with) on the iPhone and iPad. Location-based apps, like Maps and Weather, seem the slowest, as well as using third-party apps that pull data from apps I haven’t used on my iPhone for a while. The lagginess isn’t a deal-breaker, but it is a bummer. The watch is definitely the slowest Apple product I’ve used in years.

Poky performance will definitely get better as developers learn the subtleties of programming for a device that offloads much of its processing to, and gets much of its data from, the iPhone in your pocket.

I’ve spoken to a number of developers whose Apple Watch apps were incredibly slow, until they figured out the various techniques to speed performance and responsiveness. Developers who were lucky enough to get a chance to visit Apple’s Apple Watch lab and test their app on a real device, inevitably came away with some real insights and, more importantly, with a vastly improved app.

The point, early adopters, is this. The Apple Watch experience is going to improve, and pretty quickly. The performance problems pointed out in this review are software issues, not hardware issues. Meaning your Apple Watch will just get better over time, as developers learn the ins and outs of this new frontier.
