All Apple disciples can probably be in this analysis left out, but it is interesting to distinguish between non-disciples, who do not have the tablet, those who have already iPad 1 and those who have an iPad 2.
Prospects without Tablet: Here first is the question of the readiness to pay the not particularly favorable price and can. If the budget will bear, I can recommend as iPad users the device. Of course, opponents disturb the closed system to the interventions Apple, what you can do with the device and what not, to the lack of interfaces, which can be at least partially offset with übertuertem accessories (eg HDMI Adapter Apple Digital AV Adapter for iPad2 'fits on 3 - to show the contents of the iPad on a large screen TV). However, all these limitations also mean that the system is running smoothly and as a unified whole. And what I had previously never thought possible 'my Windows laptop now remains almost always in the cabinet, comes only seltenst used - photos, music (both wireless from my NAS), e-mail, surfing, Facebook, .. . Everything I use quick, convenient and immediately 'on' with the iPad. I do not want to miss it!
Whichever option you choose 'regarding storage facilities and only if Wi-Fi or WLAN and mobile' is certainly a question of money to buy, but also during operation. Personally, I think the average memory size of 32 GB for my standards for sufficient, although I save TV series, music, and photos on it. When in doubt, I replace just some content with new ones. In addition, I have decided for the 'Only wireless variant' 'I go with the iPad online, I have a wireless network either at the place where I am, or use my iPhone 4 with a T-Mobile contract as mobile Hotspot, I connect via the Internet to me. So I skip the next higher cost, the cost of an additional SIM card with a data plan specifically for the iPad.
Owner of the iPad 1 and iPad 2: You should first case look at the new feature, and here comes the main aspects, which provided even before the idea of rumors and tension: The new iPad (3) has a higher screen resolution than the 1 Series or the 2er. But it does not bring Siri with 'the language assistant, the iPhone 4S offers, but only a voice recorder. And the topic of LTE 'of mobile phone standard 4th generation' can indeed be used with the new iPad ... but not in Germany, because here the spark provider T-Mobile and Vodafone on a different frequency than in the US. The faster processor is mainly used to the new iPad (3), the incredibly sharp display to operate with sufficient power 'if this is still a power for later developing apps, can only show the time.
For iPad 1 users My recommendation is quite clear: change? Yes! Here the processor change already makes compared to 2er iPad tidy steam. The 1 Series still had no camera, the display was just compared to 3 mau.
For iPad 2 users my recommendation: change? Yes and no! The main argument can only be the display here! Although the cameras are nice, but who photographed or filmed in fact with an iPad? The processor ... see above. That leaves the display. That's with a resolution of 2,048 x 1,536 pixels really brilliant. Photos, movies and even fonts are sehbar sharper and more detailed. Especially for photographers that is certainly an argument for a 'Yes! Change! '. But if you do not have at least semi-professional claims here, the 2er iPad extends also, even more so if you do not see both iPads in direct comparison. Here I would recommend to wait for the next model, which is 'if Apple continue as previously' presented in one year.
