Yeah buddy but no my first smartphone was Xperia X10, and no Xperia Z1 vs Xperia Z bigger and better screen, better battery life, better camera and MUCH better CPU/GPU, now Z2 vs Z1 is not better by much but at least they used the latest cheap from qualcomm wich was 6 months ago Snapdragon 801 and Z2 got a bigger screen, much better battery life and much better screen quality with stereo speakers, now the only diff between Z2 and Z3 are what? 250mhz CPU speed increase and 70mhz GPU increase, I wer hoping for at least snapdargon 805, damn u Sony :-@

Had to cut down the post because it was so big.

First bolded, (as a huge Vita fan) I agree entirely, this is coming, it's going to completely change everything in the long term, this is just the start of a seismic shift in our technology (also shifting from big dedicated "desktops" "set top boxes") though there is still a market for Vita as it is showing in Japan (physical controls go a long way as far as gamers are concerned, this is also the reason 3DS can stay relevant at this stage).

I actually wouldn't be surprised if Sony have another go at an Xperia play in the future once mobile markets become more stable as far as technology goes, the Xperia player was for me, a perfect idea, that hit the market at the wrong time, and was under utilised by Sony (I think it was the Ericsson part of Sony that did it though, hence SCEI not being keen to allow too much on it under the "PlayStation" label. I think an Xperia PlayStation may well be Sony's next handheld both in phone handset and tablet form with physical controls onboard being the differentiating factor.

As for the second part, actually it's on regular phones. My HTC One (m7 so last gen) has PS Mobile on it :) but yes, it was definitely Sony's way of trying to bridge mobile phone games with dedicated handheld gaming. It actually works well there's been some solid PSM releases. Sadly because they're phone games, mainstream gaming media completely ignores these.

Unity is definitely a solid breakthrough for Sony. There's clearly a dedicated userbase on Vita who want games, iOS/Android have been getting some high profile games, however the lack of on board physical controls completely puts me off. If Sony can get these onto Vita without too much commitment from the developers, it's  an outright win win.

I don't really want a tablet, so I really hope that it does come to the Z2... or ideally my laptop, but even though it's Vaio that's never going to happen

Wouldn't they be in danger of competing a bit to strongly with the PS TV box (which is a tiny set top box which will be able to do this for any device with a HDMI input)

The PS TV has other things going for it, nearly all can be replicated by a laptop or tablet (with HDMI or I guess some good mirroring). It still has the USP of Vita games

This is nice, but would have bought the Z3 Compact regardless of this feature.

This best be coming in an update for the z2, considering the only spec difference is 2.3 quad to 2.5 in the z3 I don't think it would make a difference

I'm so glad I don't have to buy a Vita for PS4 streaming.

Portable consoles are so pointless in the era of Smartphones.

I think the main point here is that without a controller you cannot game on the Z3. The PSV on the other hand you can take with you anywhere just pull out and play. How many people will carry around a DS4 with them as they travel on public transport or commute to play on their Z3? At home you are probably better off playing on the PS4 or PlayStation TV.

Maybe if PSNOW is released on the Z3 or future Sony phones it may be worth the hassle and where a local WiFi connection is not needed, but until then I dont see this as a huge selling point.

There goes the Vita's only selling point...
