Faster processor & more RAM will be forgone conclusion come February 2011 (or Apr 2011). What people are screaming for is a front-facing camera and preferably on the long side of the bezel. How this can be implemented without breaking the classical design of iPhone, where the ff cam is on the short side, is beyond me. Windows netbook people I know want to switch to iPad for portability etc but their main 2 activities are internet/social networking & skyping where a front-facing webcam is a must.
A Native Drag & Drop Over WiFi
Say, you opened up 3 Safari tabs full of reading materials on your iMac/MacBook, and you want to continue reading all with iPad on your favorite recliner, or say, you want to show pics, clips, design ideas that you have been working on to your clients in the living room. Don't you wish you could transfer all that to your iPad with one swipe on your track pad/magic track pad from your main computer?
An SD card slot will be nice. The second iPad was revealed earlier this year, the first thought that came to my mind was : "This thing will be great for photographers who want to quick-preview their shots on the field!" And since more & more Nikon & Canon & Sony dSLRs are equipped with SD card slots, so should iPad.
Also: why can't Apple build a (rubberised) latch that opens up as a built-in stand to hold up the screen on a table and folds back flushed into the back plate?
