Maybe not?
the tl;dr: Chromebook sales are still super-strong but the 21% figure maybe way overstated.
I got the factoid wrong in my subject line, because I thought it was a measure of holiday sales rather than B2B sales for the year.
Oh well. These things are finding a niche, and I can see why. My Chromebook arrived yesterday. It will be just right for my housemate, who does not understand computers at all and is purely interested in email and web content.
I immediately saw two major problems:
1. I had to boost the power on my router because of the weak wifi card. Once I did that (and accepted the incremental toll on my home power system, which would not be a factor in the civilized world) it worked fine. That is lame for a computer that is completely dependent on an Internet connection. This thing is going to live on a table with a line of sight to my router about 40 feet away. Until I boosted the router, I could not hold the connection. I would not want to travel with a CB, or at least this model, if I depended on public wifi at all. But I could always use my phone as a hotspot.
2. The media player utterly reeks. I plugged in a "spy pen" that shoots motion jpeg with 16-bit PCM audio in an AVI container. I could play this in DOS, but it crashed the CB media player. I don't think users will stand for this over the long term, and it will really hold back their market share if they don't fix it. All they have to do is support a decent open source player like VLC, if they aren't going to develop a good one themselves.
The CB provides no access to the file system except the user's home directory and of course the Google drive. Apparently there's a hardware switch for "developer mode" that provides root access. After dealing with Linux in the hands of my friends for the past year or so, I don't think I will flip that switch. I will let Google take care of whatever is under the hood.
I got 100gb of storage on my Google drive as a perk for buying this thing.
As a web browser, this CB is excellent, smooth and powerful.
The build quality, screen, keyboard and touchpad are all fine, despite what fussy reviewers say.
This thing is in no way a replacement for a PC. As a replacement for the funky laptop my housemate and various hippie friends have been using to cadge my wifi, it should be just the ticket.
