Quite surprised that so many here are looking for 4" screens.
As opposed to what? Personally, 3.5" is my ideal. I don't really like holding half a net-book against my face.
Take an E7, bump up the RAM, screen resolution, and give me a tiered storage package (my Zune 120 is FULL, I'd like more than 16GB of storage please!).
+1! I want an E7 with the micro SD slot intact and functional, 480X800 screen, Gorilla Glass, and the N8 Camera and FM transmitter.
MS needs to take the hint on the expandable memory thing. I had more memory capacity on my old e71 than I do on my Quantum. That's just sad.
I don't need some crazy processor, or enough RAM to back bone an FPS LAN party. I really don't care about ff cameras, and I will never trust or want to have anything to do with a "digital wallet." More screen res is always nice, but 480X800 is fine in my book, it's much more important that it's done right - eg. Super AMOLEAD, Gorilla Glass, Polariser, etc..
As for a 1900MaH battery, sure, but I don't think you're gonna get it out of anything other than Li-Poly (or a needlessly thicker phone). Frankly, I don't like the idea of holding Li-Poly batteries that close to my head. What I would be much more interested in seeing is Nokia bringing to market LiFePO4 chemistry batteries like those being used in the cordless power tool industry these days (eg A-123 systems, etc.). The energy density is less, but you can SAFELY rapid charge the living H*!! out of them. They also have much less degradation of capacity over time and are less susceptible to parasitic loss. They would also hold up better (and remain physically cooler) under the strains of higher amperage drain rates you find in all this streaming and multi-tasking we're doing (or in running a WiFi hotspot once somebody hacks that for that matter ;-b )
Still, more important to me (and notably lacking from Nokia's N8, E7, N9, and Lumia) is user swappable batteries. Oh sure, I know it's a quick mini-screwdriver away with these devices unlike Apple's sealed, glued and soldered approach, but what I mean is, "hey, my battery's getting low, I'll pull another one out of my bag and swap it out. Problem solved!" I don't work in an office. I like to have multiple batteries and stand-alone chargers for them. I keep a spare brick in my car, my bag, and on the charger at home. This way, I'm never that dude running around trying to micro-charge my phone in 5 min increments just to keep it going. The reality of modern smart phones is that their capabilities are such that a friggin 4000 mAh battery could be drained in a couple hrs of heavy use. Why mfg.s are moving to sealed battery compartments both bewilders and angers me.
