Chromebooks are about to get far more capable with the addition of Android apps, but unfortunately, not all Chromebooks are going to get that capability. After announcing plans to roll out Android app support last week, Google released a list detailing which Chromebooks will be getting support for them — and there are a lot missing.

It's a pretty lengthy list, and there's a good chance that if you bought a Chromebook in the past year, you'll be in fine shape. But if you bought a Chromebook two or three years back, you may not be as lucky. Google's 2013 Pixel, for instance, isn't getting Android app support. Nor is anything from Acer's popular C720 series.

Google didn't say why some Chromebooks won't be getting support. PC World speculates that it may have to do with how Android app support is being implemented, rather than being a hardware limitation. It suggests that supported Chromebooks may be running on a newer version of Chrome OS's core code, which would be a lot of work to update older machines to.

Android app support starts in June with three laptops: Acer's Chromebook R11, Asus' Chromebook Flip, and Google's 2015 Chromebook Pixel. Over the rest of the year, it's supposed to come to over 50 additional models — the full list is here.
