Summary PROS:
Battery life - Is as promised, lasts all day on wifi.
Boot Time - First boot takes a minute, but every boot after that is the promised < 10 second boot time.
Innovative keyboard & Shortcut keys - I really love the function row on the keyboard. Everything is clearly labeled with it's functionality. No FN shift needed for volume or screen brightness !! Love it!
3g plans are reasonably priced - I have been keeping an eye on data only 3g plans and the tiers setup for the chromebook are on par or beat the norm.
Screen Backlight - Can be turned all the way down to off. Sometimes you want to turn the screen off an leave the lid open (see lid closing below)
Uploading from sd card - Uploading pics from a digital camera on chromeos to flickr is easy and straight forward (I'm looking at you ios).
Window organization and switching - Opening new tabs / windows and switching between them with hotkeys is a breeze. Highly recommend memorizing the hotkeys for maximum enjoyment of the chromeos.
Dual Core Atom - Plays back HD YouTube, not 1080p YouTube, but HD YouTube is fine.

CONS:
Mousepad - Not a fan of the oversized trackpad and the single mouse button. Right clicking is a pain and my hand is not large enough to keep the other three fingers off the mousepad, so I get a lot of stutter and unexpected mouse motion.
There is sometimes studder when scrolling webpages. If you are used to android, you won't notice the studder. If you are used to ios, the studder is very apparent.
3g activation - I have yet to get my chromebook activated, have to contact support next time I feel like being frustrated (help pages exist and support are friendly, just haven't had the time).
Doesn't like 3g hotspots - I have a 3g router and the chromebook really didn't like connecting to secure pages (https). None secure websites connected and loaded fine over the 3g hotspot.
Sleep power drain - Closing the lid sends the chromebook to sleep, overnight with the lid closed used ~10% battery.
Printing - Even if you setup their google cloud print at home, you can't print while away from home (friend's, work, printshop, etc)
Lid Closing - Listening to music on the chromebook is a pain. Close the lid, music stops. Walk away for a few minutes, music stops.
Angry Birds - Advertised everywhere in the chrome webstore but the samsung chromebook drops frames in the default HD, must switch to SD for smooth game play.
App purchases - Some apps in the webstore are free trials and require you to visit the maker's website to purchase / unlock the full app. Navigating these websites is tricky, esspecially when it is unclear if purchasing the pc app unlocks the web version (popcap).
Google services - Not fully compatible with all google services. Specifically, google music has no way to upload music from local storage (usb drive) to the cloud.
Offline apps are non existant - There is promise of google docs offline this summer, but the chromebook needs much more. Give websites the ability to store their apps local on the chromebook, there is room on that giant 16GB flash drive for a few MB of local apps.
Apps must be loaded each and everytime used - It is very annoying to watch pandora flash app load before playback starts. On ios (4 seconds) or even pc (10 seconds) the pandora loads magnetudes faster.

Bottom Line:
I think the chromebook will get better in the future. Till then I'm sticking with my ipad2. Same price range, better capabilities. Loss of keyboard and usb connectivity, gains weeks of sleep time and highly entertaining offline capabilities. Am very rarely frustrated with the ipad and has full access to google apps (docs, music, mail, etc).
