Nikon D7100 Manual Review
Nikon's D7100 has been named as the new flagship DSLR of the APS-C lineup. The camera, in a way, then is the successor to both the D300s and the D7000. Indeed, Nikon's D7000 was tough to keep in stock because everyone wanted it. With the high ISO abilities, marksman type autofocus, and excellent build quality consumers flocked to it for the great camera that it was for the price.
The D7100 is in many ways Nikon's way of showing that APS-C DSLRs still have a place in the world despite how much the ILC market has grown. The camera boasts 24.1MP
ASUS ZenBook UX51V Manual Review
This 15.6" thin-and-light notebook features an IPS display, Core i7 quad-core processor, dedicated graphics and makes for a great multimedia experience. Does lack of a touch screen kill the deal? We decide in our review.
The UX51VZ is a 15.6" notebook packing a quad-core processor, dedicated Nvidia graphics and a pair of 128GB SSDs. It's well built and has many high-end features including an IPS display with unlimited viewing angles, great speakers, nice-feeling backlit keyboard and very respectable battery life. It's ultimately a bit too expensive for what it offers (and what it doesn't offer, namely a touch-enabled display).
The UX51VZ packs a
Nokia Lumia 520 Manual review
The Nokia Lumia 520 is Nokia's fifth Windows Phone 8 handset. It's a phone which slots into the very bottom end of the range, just below the Nokia Lumia 620.
And we do mean just below - the specs of the 520 and 620 are remarkably similar, meaning that Nokia's main competition at the bottom end of the market is itself. Otherwise, its biggest rival is likely to be the recently launched Huawei Ascend W1 - a low-end handset that we're rather fond of.
Of course if you look beyond Windows Phone 8 then there's also a whole host of Android competitors such
iPhone 5 Manual review
The excitement of the rumour mill, the titillation of every leaked photo led to higher than ever levels of expectation over the iPhone 5 features, and while the announcement was greeted with some derision at the lack of perceived headline improvements, the record sales tell an entirely different story.
Given the underwhelming changes to the iPhone 4S, the iPhone 5 launch really needed to re-energise customers to prove Apple can repeat the game-changing trick it managed with the iPhone 4.
The iPhone 5 price was predictably high and continues to be so, so consumers will need to bear that in mind too when
Samsung Galaxy S4 Manual review
The Samsung Galaxy S4 is the most hotly anticipated smartphone ever from the Korean brand, and with a glut of top end features, it's the most powerful and desirable device Samsung has created yet.
One of the most impressive things about the phone is the fact the size hasn't changed from its predecessor - the Galaxy S4 comes in at 136.6 x 69.8 x 7.9mm (5.38 x 2.75 x 0.31 inches), meaning there's no extra heft to try to work with in your palm.
However, despite this fact, the screen on the S4 has been increased once
