the most reasonable features for iPad 2 on www.tuaw.com
1. Support for 900 MHz UMTS/HSDPA in the 3G antenna for wider compatibility with non-US 3G networks. Since the iPhone 4 got a quad-band antenna this year, this seems guaranteed.
2. At least 512MB of RAM. It seems exceedingly odd that the original iPad shipped with only 256MB of RAM while the iPhone 4 shipped with double that amount only a few months later. With multitasking now available on the iPad in iOS 4.2, it's crucial that Apple cram as much RAM as possible into the iPad in order to preserve the user experience.
3. 128GB flash memory on the high-end iPad. 64GB doesn't quite cut it for my needs, especially at Apple's asking price. With the difference in price between the 64GB and 128GB 11" MacBook Air being a mere US$200, and with iFixit's iPad teardown showing plenty of room inside the iPad for additional memory, the only reason I can see for Apple keeping the iPad 2's topmost capacity fixed at 64GB is a desire to retain itshigh margins on the iPad. One way around that: make a 128GB capacity exclusive to the 3G version of the iPad. The iPad's 3G chipset/antenna doesn't cost anywhere close to the $130 price difference Apple charges between the Wi-Fi and 3G iPads -- in fact, the added component cost for iPad 3G is only $27according to iSuppli.
4. Display resolution increase. Retina Display quality isn't possible now (expect to see a 326 ppi, 2560 x 1920 pixel display on the iPad 5 in 2014), but 1600 x 1200 would be pretty killer. Even 1280 x 960 would be a very respectable resolution bump over the iPad's current 1024 x 768 resolution. Coincidentally, 1280 x 960 would put the iPad's horizontal resolution in portrait mode at the same 960-pixel value as the iPhone 4 Retina Display's horizontal resolution in landscape mode, which could go a long way toward simplifying creation of universal apps.
5. FaceTime camera. This one is a gimme; we've already heard multiple rumors of a front-facing camera on the iPad 2. With all varieties of MacBooks, the iPhone 4 and the latest iPod touch all offering built-in FaceTime cameras, the iPad is now Apple's only high-end portable product that doesn't have FaceTime capability. Unless Apple comes up with some other awesome feature beforehand, it's likely that it'll market FaceTime capability as the iPad 2's main point of differentiation from its predecessor.
6. Rear-facing camera. Although this seems a less likely and possibly awkward feature, we've seen bothleaked iPad cases and insider sources claiming iPad 2 will have a rear-facing camera. There's plenty of room in the case for a rear-facing camera, so the primary concern here is usability and/or fashion sense -- is Apple willing to have millions of its users walking around looking like goofballs with their big ol' iPads held out in the photographer's stance?
