The Vizio E320i-A0

The 32-inch LED-based LCD, which Vizio says will cost about $300 at Wal-Mart and Costco when it goes on sale in October, is the cheapest smart TV I know about (at press time the online price shows as $370 from Vizio directly). That's about $50 more than the Toshiba 32C120U, but once you add a Roku or other device that price advantage evaporates. And in a bedroom setting where a TV this size is most at home, there's usually less room for external boxes, and less budget to add the universal remotes that make using such boxes just as easy as an integrated smart TV.
The advantage: 

The Vizio E320i-A0 32-inch LED-based LCD TV is a superb value, bringing Smart TV and solid picture quality in the same price range as many small TVs with neither. The Smart content selection is excellent and responsiveness was very good. Image-quality highlights include relatively deep black levels and good color. With its thin bezel, the set has a more compact, sleeker look than competitors.

The unfavorable: 

The Vizio's picture falls short of some entry-level TVs', with subpar shadow detail, and shows some discoloration in dark areas. Its Smart TV interface design seems a bit dated.

The offer: 

For people seeking integrated Smart features, the Vizio E320i-A0 is the strongest value we've seen yet among 32-inch TVs.

The LG 50PA6500

LG's cheapest 1080p plasma does some things right, particularly colors, and some not-so right, the worst being LCD-like black levels that lead to a less "present" picture. The LG PA6500's biggest problem, though, is that its competition is too good. At 50 inches, the entry-level

Samsung E450 is cheaper and a better performer despite its lower resolution; if you insist on 1080p, the slightly more expensive

Panasonic U50 is the way to go. Meanwhile the 60-inch PA6500 is among the least expensive TVs you can buy at that size, but we'd still recommend paying extra for the much better picture quality of theSamsung PN60E550.

The advantage: 

The LG PA6500 is an inexpensive plasma with natural-looking colors and solid bright-room quality. Image processing is a highlight, with correct 24p response mating well with the full 1080p resolution. This LG has a living-room-friendly appearance and it's easy to use as well.

The Amazon Kindle Fire

Amazon has completely redesigned the Kindle Fire's interface. It's sleeker, more streamlined, and feels more mature, eschewing the toy like quality the original had. Fonts are sharper and light and dark images feel more contrasted thanks to the new interface's darker tone. The carousel interface is still here, but scrolls faster and smoother, with app icons rendered in less pixely forms. Apps can be removed from the carousel at will and/or added to favorites, which appear at the bottom of the screen, negating the need to scroll through your entire catalog to find the app you want.

The advantage:
The Kindle Fire (2012) improves on its predecessor in three key ways: faster performance, a better interface with cool new features, and a significant price reduction.
The unfavorable: 
Designwise it's the same Fire from 2011 with no HD video support, no camera, no HDMI, no storage expansion, and no volume buttons.
The offer: 

The Kindle Fire (2012) takes it up a notch in value, but is tethered to the same design oversights of the original.

The PSB M4U 2

The PSB Speakers' new $399.99 M4U 2 Active Noise Cancelling Headphones may be the company's very first pair of headphones, but the engineers' smart design choices and superior sound put the M4U 2s at the head of the pack. They're fairly compact for a full-size, over-ear design and one of the few sets that can still play music after the batteries die.

The advantage: 

The PSB Speakers M4U 2 Active Noise Cancelling Headphones have really comfy earpads, keep working even after the batteries have drained, and sound great.
The unfavorable: 

The M4U 2s are a bit more expensive than most top-of-the-line noise-canceling headphones.
The offer: 

The PSB M4U 2 headphones combine above-average noise cancellation with excellent sound quality that's well worth the price for dedicated audiophiles looking to eliminate ambient noise.

The Samsung Galaxy S II 4G

The $369.99 Samsung Galaxy II 4G is an excellent example of this phenomenon. Similar to action-movie characters who have lived through countless sequels, the Galaxy S II doesn’t move quite as fast as it once did. Even so, armed with all the tools that made the phone great in its heyday, such as fast dual-core processing, a lovely high-contrast AMOLED screen, and 4G data, the Galaxy S II 4G can still throw a mean punch.

Advantage: 

The Samsung Galaxy S II 4G sports a large and vivid 4.5-inch Super AMOLED Plus display. Powered by a dual-core 1.2GHz processor, the phone also runs Android 4.0 and is 4G-capable. Camera quality is also excellent.

Unfavorable: 

Call quality could be better. The device is large and has a plasticky build.
