I wrote this up last night but waited until tonight to post it incase my opinion change for anything. I've spent a good 6 hours straight using the Sony Z tonight so some proper usage of it now

Delivery
I feel it's worth putting this in

This has been the worst 2 weeks ever. I'm very impatient and because of the custom spec I ordered, it had to be custom built over in Japan.
7th November - Ordered
11th November - Production begins
16th November - Despatched from production factory to European hub
17th November - Despatched from European hub to me
18th November - Arrived!
So just a forewarning to anyone as impatient as me!
-------
Weight
I needed a new laptop that was as thin and light as the Macbook Air, and this is bang on. Compared to the Air, it weighs less on paper, and the box it arrived in almost felt like it was empty. It's very very light!
-------
Strength
First thing I noticed when I opened the lid was the difference in build quality vs the Macbook Air. The Airs are built using a metal material (aluminum?) and the lid of the Sony Z is Carbon Fibre, so I noticed the difference right away.
You can slightly bend the lid/screen, but I can't say I tried too much! It has been put through numerous physical stress tests so I believe it is quite strong despite its flimsy touch.
-------
Keyboard + Touchpad
The Sony Z gives you a full size keyboard so that's not a problem. My only dislike is the right Shift key, it's rather small compared to what I'm used to! I've spent 6 hours writing on it tonight and typing is wonderful on it, but I do keep hitting the wrong key when I go around the right-shift area, but I'll no doubt get used to it.
The Sony Z has a pretty small touchpad compared to the Air. I measure the touchpads to be:
Sony Z: 2.9 inches (w) x 2.2 inches (h)
Air: 4.1 inches (w) x 3 inches (h)
Not a major problem for me as I use a
Logitech Anywhere MX (fantastic mouse, by the way!) rather than touchpad.
The Sony Z also has its built in gestures. I'm not sure how many, but the two I've noticed (I found out by accident as I'm so used to doing them on the Air) are pinch-and-zoom and 2-finger scroll. The manual problem tells you them all but I haven't read it.
One thing I will comment on is that the Sony Z touchpad is slightly textured. For example, doing a 2-finger scroll on the Air is flawless, but because of the texture on the Sony Zs touchpad, it can sometimes be a little "jerky".
It's also got a fingerprint reader at the bottom of the touchpad. I haven't used it but may be useful for some.
-------
Screen
I needed more screen real estate, so I went straight for the 1920x1080 upgrade... and it's gorgeous. It's really really gorgeous! Viewing angles are fantastic and it seems to have a lot more 'colour' compared to the Airs.
1920x1080 may be too much for some users. Reading at this resolution on such a small screen may be a burden for some people so I may suggest the 1600x900 instead, but for me it's fine!
-------
CPU + RAM
I went for the i5-2540M upgrade, managed to get it for free so why not! Decided against the i7 upgrade as I doubt I'd need the extra power, and I couldn't see the point in justifying the extra power/heat it'd give out (let alone the extra £180 or so).
I'm not sure how to test this for you, but I went for a quick spin with Cinebench.
Macbook Air 11" 2010: 0.70pts
Macbook Air 13" 2011: 2.11pts
Sony Z: 2.97pts
That's on the first test so it may have been better to do 3 tests and average it out but too late now (formatting my two Airs for resale now).
I've timed it booting into Windows in 18 seconds (from pressing the power button to opening Firefox). This thing is lightening fast, but more on that in the Harddrive past!
-------
Graphics
The Sony Z has an Intel HD3000 so will probably be fine for your average game. One thing to consider here is the display. The Z comes with the 1600x900 or 1920x1080 options so the resolution in a game you play may need to be reduced a little.
It does have a little secret weapon, though. The Sony Z has the option of a Power Media Dock in a
DVD or
Blu-Ray variation. Hook it up to your Sony Z and it gives you a dedicated graphics card (ATI 6550M 1GB) and a few extra ports. This runs through the Light Peak port on the side of the Sony Z.
The Power Media Dock is pretty much as thin and light as the Sony Z itself so wouldn't be a hassle to carry around if you wanted to game on the move or needed the extra graphics power.
Power Media Dock vs Macbook Air 13":
I don't have the means to test it myself as I won't be gaming on it, but these guys summed it up:
Without the Power Media Dock's extra oomph at its disposal, the VAIO Z's Intel HD Graphics 3000 gets the job done. On 3DMark 06, the laptop scored 4,068. That's comparable to other 13-inch ultraportables with integrated graphics, but the VAIO S' AMD graphics card scored a much higher 7,353.

Sound
It's a shame that Sony coupled the Sony Z with poor speakers. This is a point that all the reviews picked up on so it was to be expected. The speakers are fine for general use, but listen to some music with a bit of a beat and you'll start hearing the Sony Zs let-down. Doesn't bother me too much as I'll be using headphones most of the time.
The built-in speakers in the Air are definitely better in my opinion.
-------
Harddrive
I went for the 128GB SSD Gen3 drive, which is 2 x 64GB drives in RAID 0. I've got a single SSD on my main PC, and both of my Airs had SSDs also, but the Sony Z set up is amazingly fast in comparison!
I ran three benchmarks (not at the same time!):
I'm not too clued up on how it compares to others, but in my eyes, that's damn fast! As I pointed out above, I timed my Sony Z booting into Windows in 18 seconds.
-------
Pre-Bundled Rubbish
This is perhaps my major fault the Sony Z: the amount of rubbish Sony have pre-bundled with it, and I'm afraid there is no escaping from it!
Boot it up for the first time and you'll be presented with all kinds of DVD Makers, Media Players, Photo Galleries and other garbage. Restore it to its original factory settings and they'll come right back!
I tried installing a clean Windows 7 but it fails on "no DVD/CD device found" or something similar. I
think this is because of the Sony Z's harddrive set up (64GB x 2 in RAID) and perhaps its missing the RAID/controller drivers, but I couldn't find much on Google (perhaps my Google skills failed me or I was being too specific ('Sony Z ...').
I did find a 'hidden' folder with all the setups for the drivers though (C:\WINDOWS\Drivers\EXE)! May be useful info. for someone else at least
Uninstalling all the useless crap took 30 minutes or so but after that it seems fine. The Sony Care software will keep all of your Sony software up to date (there were 6 updates for me to download).

That's my 24 hour review of it anyway! It's a fantastic piece of kit. It is expensive so whether you can justify it or not is totally up to you. When I was originally looking around for a replacement for my 13" Air, I somehow missed overlooked the
ASUS Zenbook UX31E, and should I have seen it, I would've been very torn between the two.
Sony Z: starts at £1434
ASUS Zenbook UX31E: £1000 (?)
On a random note, I did actually manage to bag the Power Media Dock for a bargain price of £150 brand new. I was looking it up on Google a few days ago and noticed a guy in London had put one up for sale 9 hours prior to my search, so I got very very lucky and saved £200-250, so not bad. Coupled with my free CPU and RAM upgrade, I saved around £400.
Just need to find a new bag/case for it now
Any questions or anything then feel free to ask!
