Good review example:
(1st instance)Bottom line: If you are looking for an ultraportable computer, get this one.  Worth every penny and then some.  The 2010 MacBook Air gets serious about the ultraportable concepts introduced in the first MBA.  The most important change is the 11.6' screen, representing just about the smallest possible form-factor without compromise to the keyboard.  The screen is also right at the sweet spot, with a true 16:9 resolution and more pixels than the old 13' screens. I generally find it to be equally viewable as my desktop's 20', and bright enough even at 1/2 brightness for most circumstances.  This computer is anything but a netbook.  Don't call it a netbook.  The MBA is a full computer that just happens to be ultra portable.  The size and thinness really is all it's cracked up to be.  At 2.2 pounds, it's lighter than most netbooks and actually lighter than any of the actual books I carry.  It's thinner than most paperback books.  It takes up less space in my backpack than the printout of my course outlines.  In fact, its overall volume is actually smaller than that of the floppy drive in my first computer, and I owned at least one cell phone that was heavier.  When I take breaks from class, I usually hide it underneath a textbook, and you can't tell it's there.  Battery life is great and consistently exceeds my Macbook although not as good as some of the new Pros.  I frequently get through six hours of actual work between charges, keeping Bluetooth turned off and brightness around 50%.  I moved to my MBA from my aluminum Macbook, which has since become my desktop computer.  I have installed Office 2008 and 2011, which actually run better on the Air than on the more powerful Macbook, due to the fast SSD.  It really is faster than other laptops in several ways.  When resuming from suspend by opening the cover, it is ready very quickly, including reconnecting to wireless.  Booting from shutdown is incredibly fast, usually 4x faster than my other Mac.  Opening files is fairly quick, although MS Office itself is a very slow program no matter what hardware you run it on.  iPhoto is surprisingly snappy, but limited by hard drive size.  The only areas where I've noticed a performance issue are in very processor-intensive tasks like video conversion, although on those tasks it still outperformed my high-end 2006 model.  This machine is not built to be a powerhouse, but it holds its own very well, especially when compared against similarly sized units., many of which have single core chips.  Remote Disc works well, but not as well as I'd like.  I recommend using it to copy the disk onto a local file, rather than actually running even an installer program off the remote disk.  If optical discs are a frequent need, invest the $79 in the external drive.  It works very well, and still keeps the overall weight well below that of a 'regular' laptop.  Basically the performance of this laptop is fairly impressive despite not setting any records.  It shines in portability, and is more than adequate in most other areas.  Some strange weaknesses versus some other Macs: -no backlit keyboard -no ambient light sensor -no sudden motion sensor (not needed because no HDD, but still fun in third party software)  On the whole, this really is one of the best laptops that Apple or anyone else has ever made.  Get one.

(2nd instance)The update to the 15-inch MacBook Pro in February 2011 was significant.  Indeed, significant is an understatement.  Quick thanks to Amazon and Apple Stores for having these immediately available at launch.  The primary upgrade to this revision?  The processor!  Intel has a brand new architecture called Sandy Bridge, and these MacBook Pros are the first Macs to feature this technology. Some have called it some of the most significant changes to Intel architecture since Pentium 4 was introduced.  These 15-inch MacBook Pros as well as its big brother, the 17-inch, not only take advantage of Sandy Bridge, but the Quad Core i7 Variant.  Quad Core processor in a notebook Mac!  Wow.  I actually chose the 13-inch model for my personal use (only Dual Core on the 13-inch), but this 15-inch is replacing an aging iMac at the office to save space and leap over its performance.  These Quad Core Chips are amazing.  Early benchmarks are showing this entry-level 15-inch, 50 percent faster than the upper end i7 15-inch MacBook pro from a year ago.  A dramatic improvement.  Furthermore, if you're still on a Core 2 Duo machine such as the iMac I am replacing, the performance is as much as 2.5 times faster.  At least in terms of the processor.  This is most beneficial in processor intensive applications, for consumers such applications are iMovie and Garageband.  Professionals will see the new processors beneficial in any professional photo editing, video, or music work.  One downside is that due to cost, the machine still comes with a spinning hard drive standard.  In this case, the standard drive is a 5400 RPM 500 GB drive.  That offers plenty of storage, but is slightly slower than a desktop 7200RPM drive and much slower than a new, solid state drive.  You do have options.  You can special order the machine from Apple with a 7200RPM drive, or Solid State Drive.  However, what I have decided to do, is simply, when I'm ready, swap out the drive myself.  Other World Computing sells solid state drives compatible.  It might not be easy for every user, but for those with some computer experience, it is a fairly easy swap.  Then I can install a faster solid state drive, when the more acceptable capacity drives come down a bit in price.  You might also choose to do the swap yourself because you can then put the hard drive that was originally in the machine, into an external enclosure, and use it as an external drive for backup.  Of course, any damage you cause to the machine would not be covered under warranty.  Therefore, if you have any concern, you might want to see if you can special order from Apple online, or in many situations, you will find the standard hard drive to be acceptable.  After the processor advancement, Thunderbolt is the other great new technology included in this revision to the MacBook Pro.  Thunderbolt looks like the Mini Displayport that was already included on the MacBook Pros.  Indeed, it will still function perfectly as a Mini Displayport, for connecting an external display.  However, Thunderbolt is more importantly a new interface to connect external devices in the future, such as, external hard drives, HD camcorders, and perhaps even iPads, iPods, or iPhones someday.  Data would then transfer many times faster to and from these devices than it does currently.  These devices were not available at the time of the MacBook Pro's launch, but we have already heard that external drives should be available later this year with Thunderbolt connectivity.  iSight camera has been upgraded to HD resolution and Face Time pre-installed on the computer.  This gives you the ability to video chat, easily, with other Macs and notably, iPhone 4s and the newest iPod Touch with front facing camera.  The consumer software you expect to be included by Apple is once again here.  The latest version of Mac OS X Snow Leopard (operating system), iLIfe 11 including iPhoto, Garageband, iMovie, iDVD, and iWeb is all here.  OS X always includes Safari web browser, iTunes, and Mail applications too.  The average user would be good to go out of the box.  You might pick up Microsoft Office for your office document needs, or simply purchase Apple's iWork applications (Pages, Numbers, and Keynote) from new Mac App Store on your computer.  The new MacBooK Pros, thanks to Sandy Bridge technology are fast.  They will save you time, when using processor intensive applications.  Time in business, saves people money and frustration.  The average consumer might see less gains with this update as physically the MacBook Pro has retained it identical appearance, size, and weight.  Nevertheless, under the unibody, improvements have certainly occurred which result in a much faster notebook.  The fact that these 15-inch and 17-inch models now include Quad Core Processors standard is really extraordinary.  This is putting recent top of the line desktop performance, into a sleek and attractive Mac Notebook.  A breakthrough.  Recommended Product!

Bad review example:

May not be the fastest Macbook out there, but it's fast enough for normal use. I have no problem running VirtualBox with several different OS's, including Windows and Linux.  It's light and beautiful, I love this laptop and fully recommend it.

Super light, very user friendly... overall good price for what you get.  Love MAC OS X, it is all about the ease of use and seamless software and hardware integration.  Not recommended for desktop replacement!!
