Stream and the physical device - some difference is probably that the device itself is continuous at the level of the object itself palpably around him, and the stream makes it into the room where there are servers...
Mental it operated the same way.
And Yes, I2 performs this role, many have charged them that is possible

I'm not saying that Y4 is not relevant in view of this, although I think over in order to make U4.2 for example (the name is already taken V5, will grow after the main version because V5 a completely different device and the sale is not available). But now I'm here just (few months ago) vipuser upgrade V4.
Y4 started as U1, takovska system paracanoe program. A friend of my is still standing and the pair rebound to the infection, close the laptop the mouse is not working - meaning the touchpad is buggy brutally....
In version V4 one of the first was still used physically takovska system with a high voltage source and the spark gap, but it was hard and unstable, and then I'm working with quantum converters, when there is a data stream and processed at high speed and has smazannost with the flow of energy for example, as a pair, moved on to the quantum implementation of the seminar subject 3 wore it without a box and some webinars - 72 MHz CPU type cortex, powered by USB gives the effect of micro V4 more powerful than maslowska system in order, special code changes do Y4 and Y4 large - two cores working in tandem.
Then I started preupgrade all aprati (actually replaced everyone who bought the device on the new version).
Recently got a fun update that I also upgraded all for free, well, who wanted. People wrote reviews about it in terms of those who are sensitive and well felt like last version and the new. IMHO these reviews are in the V4 branch.
That just left me, 4 Y4, 3 upgrade and a new.... well, last week I think.
... Yes... so, now I'm the new version will not do that, and I2 the OTHER but good job with the same work;
The difference here is the V4 gives the HF energy, which then transform of the product that you need and in other bands.
U2 - wide strip and the operator can switch to something different, while V4 is working quietly somewhere on "cleaning the room" is that mental it will switch and it still will not shut off unless the direct command of other consumers of products of the operator.
Y4 in micro version cheaper. Full now seems identical to the I2 without the discount (I don't remember the prices, forget after writing messages on them).
I2 is substantially more flexible and powerful (and widely as possible), and Y4 is a quiet stable and just type substation for products.
Rather, I would recommend to have a second I2, which does not switch on everything, not take away from his place, and so on. But the urgency of the V4 that does not change.
Once something like this.
Because for technical reasons I will not be able to do U4 until T2 ( in sense T2 in the next couple of weeks should do to You, and Y4 is already on the November fall), you should probably first look and feel.
Of course, I recently affectionately kept replacing Y4 in hand and thought that it would also be necessary in a personal bag to have in addition to I2, but then I thought this was a blessed break and just feeling good

in the broadcast he certainly me included.
Oh, and translational of course You can connect without waiting.<
