My new Chromebook w/ 3G wireless (via Verizon, 100 MB/month). Currently $310 at NewEgg, $230 for the wifi-only version. There are sub-$200 models from other manufacturers.
It’s great. Netflix and Hulu work OK - a little stuttering on Netflix occassionally. All the Google Apps work fine: Gmail, Calendar, Documents, etc. There are also text editor apps for light coding. Worst comes to worst, you can edit in GitHub itself. There’s a not-so-great SSH client. A last-resort BitTorrent client, too.
There is Flash built into the Chrome browser, so the usual video sites (YouTube, Vimeo, DailyMotion) work even without using HTML5 video.
Photo editing is a weakness. There are no apps which directly support RAW files: you have to use PicasaWeb, which is now integrated with Google+.
Flickr used to support RAW files of various formats, but does not seem to, anymore. Attempts to upload a Nikon NEF file failed: the fancy uploader just refused it, and the basic uploader took it but only grabbed the JPG thumbnail.
Picasa does accept NEF, and converts it to JPG. It has basic online image editing, like Flickr does. This is how I converted the NEF to JPG to post the image above. Conveniently, this Chromebook has a built in SD card slot, so I can just pop the card in from my camera.
I waited a few weeks to update my Hackintosh from Mac OS X 10.8.2 to 10.8.3 in order to make sure any issues were dealt with by others. Instead of using Software Update from the App Store, I downloaded the Combo Update package from Apple. Using the Combo Update is the recommended way of updating Hackintoshes. However, there were quite a few reports of successful updates applied by using the App Store updater.
In any case, after applying the update, my Hackintosh would not boot. I basically had to go through the entire build process again. I actually "doubled up" because there is a new version of Unibeast for 10.8.3. So:
Remove graphics card
Use Unibeast 1.5.3 to reinstall Mountain Lion 10.8.2
Boot safe mode (-x) from HD using Unibeast, then re-download Mac OS X installer from App Store.
Download new Unibeast 1.7.0 from Tonymacx86, and create new USB Unibeast flash drive.
Boot from Unibeast 1.7.0 to reinstall Mountain Lion 10.8.3
Reboot from HD using Unibeast, and run Multibeast. At this point, I still couldn't boot from the HD without Unibeast.
Reboot from HD using Unibeast, and install Chimera 2.0.1
Reboot from HD without Unibeast. (Success, finally.)
Turn machine off, reinstall graphics card, and reboot a final time.
Holy smokes. That only took me a week to figure out, after going through many iterations. Well, at least I'm still saving 30% or more compared to a Mac Pro.
