Apple iPad 2 vs. Samsung Galaxy Tab 10.1 vs Samsung Galaxy Tab 8.9 (google android repair)

The tablet wars have just heated up immensely and we might be on the verge of an explosion right now, as Samsung has just revealed its two new weapons – the refreshed Galaxy Tab 10.1 and the Galaxy Tab 8.9. We already told you what they are all about and now comes the time for the big question – how do they compare to the new tablet blockbuster – the iPad 2?

A couple of weeks ago, Samsung's CEO said that he feels the Galaxy Tab 10.1 felt "inadequate" to the newly released iPad 2 and that some changes needed to take place, one of which was the pricing. I can only say bravo to Samsung for making such radical of a changes in such a short period of time. They actually managed to make the new Tabs even thinner than the iPad 2, measuring at just 8.6mm thickness.

And here comes a head-to-head comparison of the two new Samsung slates and the Apple iPad 2 on some of their most important features.

Of course this table doesn't tell the whole story – there are other things such as app count (where the iPad 2 is a leader by some distance), build quality, display quality etc. Head to the comment section and tell us what's your take? Which one of those relatively equally priced bad boys would you give your hard earned cash for?

Android, Apple iPhone 4: What is Super WiFi? (Tech, news, report, Auckland, "iPhone Repair")

The FCC just cleared a path for a new generation of "Super Wi-Fi" technologies. Sounds great! But what the heck is Super Wi-Fi?  http://tiny.cc/superwifi
Super Wi-Fi is still Wi-Fi...
It's not as though Super Wi-Fi is some entirely alien concept. For all intents and purposes, it's Wi-Fi! The same kind of wireless data transmission you use around your apartment or at the office or waiting in line at Starbucks. It's just much, much more powerful.

...but on a new spectrum...
As John explained previously, pretty much all Wi-Fi activity takes place on the same 2.4GHz or 5GHz frequencies. For the first time in 25 years, though, the FCC has opened up a sizable new block of unlicensed spectrum, this time between 50MHz and 700MHz.
...that lives in between your TV channels...
Ever since television went entirely digital, folks like Google have been lobbying, literally, to free up the airwaves between channels. The so-called "white spaces" would otherwise have been lying around unused or been subject to prohibitive regulatory precautions.

...that's much more powerful than what we have today...
Unlike current Wi-Fi airwaves, whose reach can be measured in feet, the spectrum that would carry Super Wi-Fi would be able to travel for several miles because of that lower frequency. Through brick walls, even—something your Linksys really struggles with. You can also anticipate download speeds of 15Mbps to 20Mbps—about as fast as a cable modem.
...that shouldn't interfere with your regularly scheduled programming...
Back in 2008, when the white space plan was first approved, the biggest concern was that using these airwaves for data transmission could interfere with TV signals. To mitigate those fears, white space devices will be required to query a special geolocation database, ensuring no signals are crossed.

...and that will have (literally) far-reaching benefits...
The advantages are already apparent. Google, for instance, already has a trial running in a Logan, Ohio hospital that's giving first responders and the hospital grounds alike super-speedy broadband. Wilmington, NC uses white-space to send real-time feeds from traffic and security cameras. And eventually, you would potentially be able to access your home Wi-Fi from several blocks away.
...though maybe not for a while.
So far, most of what we know about how the white space will be used is based on conjecture. There may be some proof-of-concept devices early next year at CES, and there may be more mass production of products in a year or two. But the first Super Wi-Fi projects are likely to be medical, municipal, large-scale. How long it takes for us to be always connected from anywhere and anything? That's up to the inventors and entrepreneurs to decide.
