There's little on the outside to suggest a massive upgrade over the Galaxy S III. On the other hand, the spec sheet implies a significant leap forward, improving on just about every aspect of the hardware and adding plenty of neew software features. As usual, the truth is somewhere in between and our job today is to put a finger on it
Design and handling
The Samsung Galaxy S4 design is the part that has changed the least compared to the Galaxy S III. The smartphone uses the same Hyperglazed finish, on account of which the predecessor was bashed for feeling like a plastic toy rather than a flagship proper. And the Galaxy S4 will most likely receive the same criticism. After all, it doesn't come anywhere near the premium feel of a Sony Xperia Z, let alone the HTC One.
This is not to say though, the Samsung Galaxy S4 looks worse than its predecessor. The new texture gives it a more serious and stylish look, while the improvements to the design also contribute to the overall appeal. The slimmer bezels leave more space for the brilliant screen (more on it later), while the slimmer body has a more high-end vibe. We are positive too that many will appreciate a black paintjob.
The size of the Galaxy S4 is a marvelous achievement, which should not be overlooked. The smartphone is the exact same height as its predecessor, but is 0.8mm narrower, 0.7mm slimmer and 3g lighter, while featuring a 0.2" larger screen, a higher-capacity battery that's still removable, and a host of new sensors and radios.
We guess Samsung has to share some of the credit with Corning and its new Gorilla Glass 3 that the Galaxy S4 employs. Based on a completely new glass composition, the third generation of the popular screen coating offers increased impact and scratch resistance, so Samsung could probably get away with using a slimmer shield, while maintaining the same level of protection. In fact the early tests are showing that the Galaxy S4 is actually harder to scratch than its predecessor.
At any rate, despite all the new features it introduces, the Samsung Galaxy S4 is easier to handle than the S III. It also feels more comfortable in the hand than the HTC One and that one only has a 4.7" display. Samsung has shown to competitors that a 5" screen doesn't necessarily make for an unwieldy handset.
1080p Super AMOLED display is what geeks' dreams are made of
One of the most important updates that the Samsung Galaxy S4 brings is the new 5" Super AMOLED screen of 1080p resolution. While it does have a PenTile matrix, the 441 ppi pixel density makes sure you won't be able to spot the hated cross-hatch pattern.
The defect wasn't easily spotted on the Galaxy S III either unless you looked from a closer-than-comfortable distance, which is to say it was as good as invisible to the naked eye. The design of the PenTile matrix has been changed too, so now green sub-pixels are twice as many as blue and red sub-pixels and the arrangement is changed. This however matters little to anyone not armed with a microscope.
What you should take away from all this is that the final weak point of the Super AMOLED screens has been taken care of and the Galaxy S4 offers image quality like no other smartphone on the market. Its impressive contrast and almost perfect viewing angles make everything on the screen pop-up regardless of your view point.
The color saturation is beyond the reach of any LCD out there, which make even the dullest image appear remarkably vibrant. Still, if you are not a fan of the oversaturated look of the AMOLEDs Samsung gives you the option to tune down the saturation to more natural levels and enjoy the best of both worlds.
The brightness levels of the Samsung Galaxy S4 is slightly higher than the rest of the company's AMOLED displays, which is to say not very high. However, due to the low reflectivity this doesn't affect outdoor performance.

Of course, Nokia showed that a brighter AMOLED can do even better in direct sunlight, but the gain isn't dramatic. We'll make sure to do a sunlight legibility test for the review and find out all about that.

Cheap Windows 8 upgrade may require your Windows 7 key
Microsoft might ask you to enter your Windows 7 key during the process in order to qualify for the $14.99 upgrade.
People who bought a Windows 7 PC on or after June 2 can upgrade to Windows 8 Pro for just $14.99, but they may have to supply their Windows 7 product ID.
Microsoft kicked off registration for the $14.99 deal in August. Anyone who bought or will buy a new Windows 7 PC between June 2 of this year and January 31 of next year can upgrade to Windows 8 Pro for that special price. Shelling out the $14.99 lets you download a copy of the Windows 8 Upgrade Assistant, which helps you install the new operating system.
The deal cuts $25 off the standard Windows 8 Pro upgrade, which costs $39.99 to download for Windows XP and Vista users and Windows 7 users who purchased their PCs before June 2. People who want an actual installation disc have to cough up $69.99.
The $14.99 upgrade process typically asks you to enter the name and manufacturer of your Windows 7 PC, and the date you bought it. You'd then receive one of two notices, either a Success message telling you that you qualified, or a Sorry message breaking the news that you didn't qualify.
But in my experience, that process seemed a bit buggy.
I tried to register for the $14.99 upgrade last week with three different PCs, all from Lenovo and all purchased after June 2. One PC qualified for the upgrade, but two did not, with no explanation why. I tried the process a few times with the two failed PCs, but each time I came up empty.
I again tried the process on Tuesday and this time discovered that Microsoft now asked me for my Windows 7 product ID as additional proof. After entering the ID -- success. I now qualified for Based on various online comments, other recent Windows 7 PC buyers were bumping into the same initial problem of being rejected for the offer.
However, the requirement for the Windows 7 ID seems to be random.
Some people told me that they were asked for their Windows 7 key in the past and pointed out that this is not a recent change. But others have said they've never been asked for the key, not even in recent attempts. I contacted Microsoft to ask about this inconsistency, and a spokesperson e-mailed me the following statement:
The Windows Upgrade Offer process will dynamically adjust the registration process based on a variety of factors that take into account individual, local market, and global circumstances. Some users are required to provide additional purchase details online or offline in order to validate their registration. If eligibility cannot be determined using the online process, customers may need to contact customer support and provide proof of purchase to support.
So it seems to be a hit or miss process as to whether you'll have to supply your Windows 7 product key. But in my experience, providing the key was the only way I could qualify for the upgrade.
The offer limits you to five PCs, and you can install the Windows 8 upgrade on any PC, not necessarily the one with the product key that you use to qualify. The $14.99 and $39.99 deals both end January 31. So those of you want to upgrade to Windows 8 Pro should take advantage of those prices while they last.
