Dell Streak 7 (T-Mobile)

Welcome to a laptop battery specialist
of the dell laptop battery

The Streak 7 is a pretty straightforward slab. The glossy black front panel slopes downward on the left and right sides to improve gripability. The sides and back are made of a dark charcoal plastic, with the back carrying a subtle diamond pattern emblazoned with a silver Dell logo.

At 7.9 x 4.7 x 0.5 inches and weighing 1 pound, the Streak 7 is a little larger and heavier than the Samsung Galaxy Tab ( 7.5 x 4.7 x 0.5 inches, 13.4 ounces) and the Viewsonic ViewPad 7 (7.1 x 4.3 x 0.45 inches, 13.2 ounces). The slate felt light but solid in our hands and didn't creak when we pressed on it, as some cheaper tablets do.

Like the original 5-inch Dell Streak, the chassis was designed with battery such as dell 312-0393 battery, dell Latitude D800 battery, dell Inspiron 8500 battery, dell 8N544 battery, dell Inspiron 8600 battery, Dell Precision M60 battery, dell Inspiron 6400 battery, dell Inspiron E1505 battery, dell Inspiron 1501 battery, dell GD761 battery landscape-oriented use in mind. Unlike the Galaxy Tab, the front-facing webcam is on top when the tablet is in landscape mode. A volume rocker and the power button sit at the top of the chassis. On the left side are a speaker and 3.5-inch headphone jack. A full-size SD Card slot and a SIM card slot sit underneath a flip-out door on the right of the unit.

Like many tablets today--including the Samsung Galaxy Tab--the Dell Streak 7 uses a proprietary docking port to charge or connect to your PC. The device comes with a single docking-port-to-USB wire and a USB AC adapter for charging. Unfortunately, though you can copy files to or from its internal memory, you cannot charge the Streak by connecting it via USB; it can only get power from the wall.

The 7-inch 800 x 480 glossy screen has strong viewing angles both from extreme left-right and titled positions. However, the glossy surface, which is made of durable Corning Gorilla Glass, is a fingerprint magnet and shows lots of imprints when held up to a light source. Colors look true, but are not nearly as vivid as those produced by the Galaxy Tab.

Unfortunately, the 800 x 480-pixel screen resolution is a huge disadvantage for the Streak 7, particularly when compared to the Galaxy Tab's 1024 x 600 display. When you consider that most Android phones have the same resolution, the Streak 7 lacks one of the most important benefits slates have over handsets. This paltry amount of screen real estate effectively prevents the Streak 7 from having dual-paneled apps such as the Galaxy Tab's Calendar, or from showing most web pages at full width without zooming out.

Also, because it fits fewer pixels into its 7-inch panel, each dot is larger. Graphics in games such as Angry Birds and Asphalt looked much less sharp than they did on the Galaxy Tab.

Like all but the cheapest tablets, the Dell Streak 7 uses a capacitive digitizer that supports multitouch gestures. In our testing, the device was responsive to our taps and pinch-to-zoom was extremely smooth in all applications, particularly the browser.

The Streak 7's 1-GHz Nvidia Tegra 2 CPU insures that it can play any kind of video you throw at it. In our tests, downloaded videos, including a 1080p Quicktime trailer of Iron Man 2 and a 1080p WMV file of Coral Reef Adventure, were completely smooth and sharp. However, the Streak 7 does not come with a pre-loaded video app, so in order to play Quicktime and WMV files, we had to install third-party applications such as Act 1 or Vplayer. However, the Streak was able to natively play 720p videos we recorded with its built-in camera.

We were particularly impressed with the Streak 7's ability to play online Flash videos. When we were connected to T-Mobile's 4G network, we streamed both a 720p clip of Glee from Fox.com and a Flash Green Hornet trailer from Sony.com. Amazingly, both videos started almost immediately and streamed smoothly, though we noticed a little blockiness in the picture.

For a 7-inch slate, the Streak offers really strong audio playback. When we tried playing both the bass-heavy R&B tune "Forget Me Nots" and the guitar-dominated "Back in Black," sound was clear if not overly rich. At maximum volume, the music was quieter than most netbooks we've tested, though loud enough to fill our small living room.

Like the Samsung Galaxy Tab and many other devices, the Dell Streak 7 comes with the Swype keyboard pre-installed; this lets you draw a continuous line between letters to form a word. If you don't like drawing lines or find it difficult to pick up, you can just tap the individual letters as normal. However, if you start tapping too quickly, Swype will think you are drawing a line and start connecting the keys.On most tablets and phones, users who don't like Swype can disable the software in the settings menu and get a standard Android keyboard instead. Unfortunately, we were unable to turn Swype off until we installed Better Keyboard (a third-party app).

Overall, we were able to type effectively with one or two fingers. Because the keys are so large in landscape mode, we only rarely hit the wrong letter. A blue glow appears around each key as you hit it, which lets you know your tap was registered. The Dell Streak 7 also has haptic feedback, which gives you a small vibration when you hit each key. You can turn this feature off in the settings menu, but we found that having it on made it even easier to tell that we'd hit the right key.
