Unlike a conventional laptop where unless you are in a plane (Horrible place for using a laptop BTW) these days battery life isn't of prime importance --even "out in the field" car adaptors are fine and you are usually using a laptop with a whole load of other gear - particularly if you are measuring environmental / engineering data.
A Tablet on the other hand is designed to be a much more portable device from the outset and in this case Battery life IMO is much more important.
6 Hours though with an I7 processor doesn't actually sound too horrible which ever way you cut it -- I'd imagine that a tablet with this type of processor in it would in any case have a decent "Power saving mode" when using it for typical "tablet" type stuff, and the real drain would only be experienced when working in "Serious Laptop Mode" in which case as for those using a laptop would probably have access to power supplies fairly often. (The tablet would get really hot also with an i7 in it -- my Galaxy IIIs phone gets surprisingly warm sometimes - European model with the QUAD processor rather than the US model with the DUO -- can't say I've ever needed the power of the QUAD in the phone though !!).
I can't see this feature being a deal breaker -- Price though most definitely when you look at some of the great really thin "Ultra book" laptops out there now - still selling by the truckload --so this segment of the laptop market is by no means dead yet.
I can't wait though to actually see one of these in the flesh - and we all know after a while these products will be discounted by re-sellers -- so it could be "game on".
One thing is for sure this will definitely be an Ipad exterminator unlike the RT which is a bit like a toy rather than a real computing device -- we'll see however.
I still really can't see why you'd need an i7 processor in a tablet -- I'm managing just fine with an i3, SSD and 8GB in my laptop and even for things like photoshop it performs just fine. Due to the size limitations of the tablet form I'd imagine an SSD would be fitted as a matter of course, and memory would have to be decent as these things aren't "expandable" like normal PC's or even some laptops.
The storage size in the spec is also unclear -- does 128GB mean 128 GB RAM or is it 4GB "Conventional RAM" and the rest by a built in SD micro card or whatever.
128 GB Internal RAM is probably grossly overkill anyway - unless I'm running around 8 VM's concurrently I don't have any problem with 8GB ARM. - I do need removable storage though whether its via a USB ext drive, a USB flash drive,an SD card (or micro SD) or a combination of all 3. If you don't have external storage then you'll be forever syncing this thing with either a phone, or your remote (work or home) computer.
I really don't see a tablet user either for instance running 3 or 4 Virtual machines concurrently or hooking it up to an industrial cutting machine for metal working etc -- tasks most laptops can do with ease.)
I'm not trying to be negative about this device --I really am curious to see how it fits in to "general computing" today. Maybe users will find new applications for it that we haven't even thought about yet.
So I can't wait to see this thing out in the flesh. Will judge it more then. All I'm going on now are basically "rumours and leaks". I have yet to see an actual RETAIL production model of one of these yet.
