Firstly you must be aware of what you are buying, this is a Chromebook, its not a Windows laptop, its not a Macbook, it will NOT run any windows or other OS applications, it is not iOS and it is NOT Android either. Also don't expect to plug in bluetooth adapters or other hardware (except mices and keyboards) and have them work, they likely won't.
Chromebooks pretty much run the Chrome browser that you can download for your bigger desktop computer (PC or Mac) and thats all.
Now that might sound like a major limitation but that is where you would be wrong.
Its amazing what you can do in a web browser window these days, from full on word-processing and spreadsheets, to even graphics editing (Photoshop style) with Chrome Apps such as Pixlr. There is a world of apps out there, go download the Chrome browser and check out the apps and the extensions, all can be used on your Chromebook.
Now, there are those that will whinge that it doesn't play MKV or AVI files, but it does play MP4/M4V files which the majority of the world is now using, its a case of knowing what this machine does and realising that it IS a compromise of price over function.
As far as I am concerned I have a great looking, fast running, no-maintenance, secure, virus-free laptop for a ridiculously low price. I have tons of movies stored on the 320Gb hard drive for when its out of earshot of Wifi, all of my other files are on Google Drive, you get 2 years (YES you heard me right) with 100GB of space...and when that 2 years is up and if you CHOOSE not to pay for Google Drive storage your files DO NOT disappear like some suggest...you just cannot add any MORE to the files you currently have. that seems very fair to me.
Music, load up to 20,000 tracks into Google Music...for free, then play them in the browser, they will also be available then on your iPhone or Android phone via the Google Music apps for those devices.
Gmail, Calendars, Calculator, FTP access, even application development can be done via the browser these days and if that isn't enough, connect to your home desktop using Google Chrome Remote Desktop and use your home PC over the internet, securely and for free.
Whats not to like about this laptop?
Is it for everyone, of course not, nothing in life is, but at this price, with these functions and more, you'd be mad not to.
There are tutorials, on YouTube funnily enough, that show you how to dual boot with Windows and Linux (Ubuntu) if you wanted to run it on this machine, that is due to its hard drive and memory, which can both be expanded unlike most other Chromebooks.
Some people also moan about its 10 second boot up compared to the Samsung range's 6-8 second boot up...erm, thats from a cold boot, machine totally off....I booted it up from cold the first time I got it, once after the updates came through for the machine and since then its never been powered down, doesn't need to. You just close the case, it goes to sleep, open the case, it wakes up.....in less than a second. So boot times are irrelevant unless you want to totally power it down each time, in which case your likely in the less than 1% that will ever do that.
Updates, this machine auto updates, silently, in the background, It can be recovered if anything goes wrong.
If you store your files on Google Drive (like your meant to) and not the hard drive, if you break, loose or have the laptop stolen all you need to do to get back to where you were before it was stolen is log into a new chromebook, it will restore everything because its all stored in the cloud.
Worried about 'the cloud', don't be, its been around for a long time now, gmail is 'the cloud', when did you last loose your gmail emails? Thats right, never. So why worry? If you want to be prudent, back them up on your desktop machine to somewhere else.
Worried about not having internet access, lots of apps will work offline, its likely your smartphone can do wifi tethering, so you might have a wifi hotspot in your pocket right now to use with this machine, so why spend extra on a 3G machine which will need its own account, more money, just use your phone or a local free hotspot.
Heard some bad things about this models keyboard...erm...did these reviewers even USE the laptop, there is not a thing wrong with the keyboard, its almost a copy of every other 'chicklet' style keyboard out there, including this iMac that I am typing on just now, its a great keyboard.
I love it, great laptop, great price.
