As crazy apple production fans, when apple inc. release new gadgets, people just can't stop themselves replacing old generation for the new one, like most of us holding ipad2 instead of original ipad. That's our natural reaction, cos basically we think new things must have more functions and easier to operate, that thought gets some point, but the truth maybe, I'm not gonna say "shock" you, at least will let us think they are playing some kind of tricks with us, if you know weakness of ipad2, you will definitely guess they'll be holding out for version 3.

So there is no need to acclaim how wonderful ipad2 is. Apple could have gone further, which is why many with first-generation devices will be happy to hold out. As Steve Jobs alluded to during yesterday's event, the company didn't really have to add much. That said, there are five specific things Apple could have added but didn't.

1. Retina Display. It's a high-density pixel display that packs in about four times the number of pixels as standard displays. but alas the screen that ships in the iPad 2 is the same resolution as the first. It has been proven the effect of having a resolution that high in such a small area can have a dramatic effect on detail for things like text, and detailed imagery.

2. An SD card slot/USB port. Rumors began circulating as early as September of last year that Apple was working to bring a mini-usb port to the next iPad. Extra fuel was added to that fire with a number of third-party case manufacturers making early iPad2 case designs with an extra hole near the top. This later turned out to be the revised placement of Apple's microphone, which had previously been located next to the headphone jack. So could Apple add either one of these to the next model? Perhaps though that would give people less of a reason to shell out $29 for the connector kit.

3. Thunderbolt connectivity. Thunderbolt could end up being the answer to bringing that speed back, though with new MacBook Pros only sporting one Thunderbolt port, which is also used to plug into external displays, it's not quite at the point of being the kind of casual plug users will have open and available at all times. That could certainly change a little farther down the line though.

4. Near Field Communications technology. Rumors of Apple testing NFC chips in iPhones began as early as August, then a report by Bloomberg back in January claimed that Apple was working to bring the technology to the next generation of the iPhone and iPad. NFC chips could then be used as a payment option, or with applications to ferry over their data from one device to another.

5. 4G. By comparison, Apple competitor Motorola plans to offer a 4G modem upgrade to owners of its Xoom tablet in the second quarter of this year. This will require that users send back their tablet to the company to get it retrofitted to receive the 4G signal.

Although, now that some of us already in that circle, what we need do is use them adequately, so if you like to watch videos on your ipad or ipad2, you may need a ipad video converter, it can convert all kinds of formats to ipad. And you may interested in ipad hd video converter, add photos to ipad without deleting old ones and how to jailbreak ipad.

How can you make your ipad stay on line? You maybe know how to surf internet with your ipad, but it has some limits, perhaps most of us use built-in Wi-Fi, what problem do you get? Do you notice that you can't connect the internet at some place? Or when you are out of Wi-Fi hotspots? Or it just freeze when you watch videos or whatever else? When that happens, how do you feel? What do you want to do? I gotta say, it sucks, but apple inc. always can figure it out. Of course, Wi-Fi is powerful, but sometimes you need another way to stay connected.

All iPad models come with built-in Wi-Fi. If you want to access the Internet in more places, choose iPad with Wi-Fi + 3G and sign up for 3G data service from AT&T or Verizon - right on your iPad. Wi-Fi or Wi-Fi + 3G.

Which iPad should you choose?

iPad with Wi-Fi is ideal if you have a wireless high-speed Internet router in your home, or if you'll be using your iPad near a wireless hotspot - in a coffee shop or school library, for example.

iPad with Wi-Fi + 3G includes Wi-Fi connectivity as well as 3G connectivity. 3G uses cellular signals - the same signals your cell phone uses - to connect to the Internet. Choose an iPad with Wi-Fi + 3G if you'll be spending time in places without Wi-Fi hotspots, such as outdoors or on your morning commute.

Tip: chose your ipad by carrier.

If you decide on an iPad with Wi-Fi + 3G, be sure to select the model that corresponds with the carrier you'd like to use for 3G service. The iPad model you purchase is specially configured to work with either AT&T or Verizon - not both. So while you don't have to activate 3G service right away, you should choose your iPad with Wi-Fi + 3G according to the carrier you prefer.

When you decide to activate 3G data service, you can choose the amount of data per month you want to buy - with no long-term contract. So if you have a business trip or vacation approaching, just sign up for the month you'll be traveling and cancel when you get back.

What you gonna do:

1. Sign up.
Tap Settings and choose Cellular Data. Then select a plan and enter your payment information.

2. Check your usage.
iPad lets you know when you're about to reach your data limit so you can add more.

3. Adjust your plan
If you want more data, you can sign up for a different plan - or cancel 3G data service altogether - anytime, right from your iPad.
