Don't necessariily be put off by the lack of Windows. Chromebooks are a different idea. They do not do some things as well as Windows or Mac, but they do others a lot better.
Engadget describes the latest Chromebook as "80% of the MacBook Air experience for 25% of the price." Engadget also praises the build quality of the new Samsung Chromebook as "fantastic."
As you know, Chromebooks emphasize storage of data in the "cloud" and execution of applications on a remote internet server, rather than locally on the Chromebook. By off-loading services to the internet, Chromebooks do not require much local storage or processing power. That gives them long battery lives and relatively cheap prices, which are their chief advantages. The real keyboards are good for productivity applications, as you have noted. Boot times are fast. A Chromebook is safer for surfing the internet than is Windows.
The primary disadvantage is that they require a fast and always-available internet connection. Because the idea is that the apps to be run will be online, there are only a few apps available to install locally on the Chromebook.
My OH wants it for Christmas, but after looking at the specs, I have my doubts.
Why does he want one? What use does he intend to put it to?
For me, hacking away at a machine, installing alternative OSs, and making it do things the manufacturers never intended is half the fun.
But, for most people, if it isn't Windows or Mac, it's worthless and they don't want it (as you can see from the posts above).
I feel more or less comfortable with the hardware, i.e. the memory, the processor speed, etc. Google hasn't told us how it boot, however. Can a user boot up under a USB stick or a USB external drive? Is there a BIOS?
Yes, you can boot from a USB stick or external drive.
Chromebooks use a UEFI BIOS, similar to the new Windows 8 computers. They also implement secure boot like Windows 8. Normally, that would mean that you could not boot anything other than a Google-signed version of ChromeOS. However, unlike Win 8, Chromebooks have a hardware switch to turn off secure boot, enabling you to boot alternative OSs. That's important, because they run some alternative OSs quite well.
Ubuntu 12.04 runs particularly well on the new Chromebook, and is particularly fast. There is even a special version of Ubuntu ("ChrUbuntu") specifically tailored to the Chromebook.
Here are instructions for installing Ubuntu (ChrUbuntu) on the new Samsung Chromebook. You may install other OSs as well, of course, but they must be compiled for the ARM processor, which is what the new Samsung Chromebook uses.
I see that they have based it on LInux, and that it has a Portage tree. I have some experience with Gentoo, so I could figure it out. But some say that the Shell will not allow but a few commands, making downloading through the Portage tree a challenge if not outright impossible.
Yes, ChromeOS is (yet another) implementation of Linux. I cannot speak to the flexibility of the ChromeOS shell, but it is easy to install alternative OSs on the latest Samsung Chromebook, as discussed above.
So what do you think?
Could a user find a workaround, and put Gentoo Linux on it? Or would the firmware prevent this?
As discussed above, there is a hardware switch that must be flipped to turn off secure boot. Except for that, there is no impediment to installing other OSs on the Chromebook. For the latest Samsung Chromebook, however, you must make sure to use an OS compiled for ARM processors. Previous Chromebooks used Intel Atom processors, but the latest Samsung Chromebook is ARM.
There is a version of Gentoo for ARM, and
it has indeed been ported to the Samsung Chromebook.
Would it be smarter to just buy a Netbook?
A netbook would make more sense if you need Windows (e.g., for games). A netbook would also make more sense if you wanted to run local apps (like office applications) and you were uncomfortble installing operating systems on a PC. A netbook would also make sense if you need a huge hard drive. The Chromebook has only a 16 GB SSD, plus whatever you can save to a full-sized SD card.
But, the Chromebook offers a much bigger screen than a netbook, as well as a full-sized keyboard, for the same price. It also offers a longer battery life and more secure surfing of the internet. It is faster both at boot-up and in routine operations. The Chromebook does not ship with many local apps installed, nor are many available for ChromeOS. A full suite of such local apps are available, but only if you are comfortable installing and using an alternative OS.
The Chromebook may be a great choice for you if you don't mind learning new things and experimenting. If you are like most people, however, you should search around for a cheap Windows laptop. I saw a Dell Inspiron Win 7 laptop at Big Lots just a couple days ago for $250. I don't know the specs - it's probably not particularly fast or impressive at that price. But, it's a perfectly usable machine and it's what everyone else is using.
