The days of the 3G brick are numbered, with Samsung's Z510 joining the Motorola V3x in the slim and sexy category.

Design
The design of the Z510 has been heavily influenced by Motorola's enormously successful v3 (RAZR) range. The squared contours, keypad layout, shortcut keys and outer display are all, well, let's be charitable and say "inspired by" the RAZR, but Samsung's model has enough of its own charms to be more than a mere copycat.

The main difference looks-wise between the two phones is that the Samsung model features a rotating camera on the hinge of the clamshell, whereas the V3 camera is embedded in the Motorola's lid. The Z510 is also 1mm thicker than the original 2.5G RAZR, but almost 5mm slimmer -- and at 98 grams, 27 grams lighter -- than the 3G V3x.

One multitasking port on the right of the phone serves as the socket for charging, USB connection and stereo headphones. While this convergence makes for a more streamlined look, it also makes it impossible to connect the phone to a PC while charging it.

Befitting the focus on multimedia, there are three buttons on the clamshell cover for music playback and a camera shortcut key.

The keypad lacks the novelty of the RAZR's Tron-esque, neon blue-accented design, preferring a sleek, shiny black and brushed silver finish. The only problem with this is that the ebony number keys tend to become sullied with smudges after a number has been dialled.

Features
When we switched on the Z510 for the first time, we were immediately smitten with its dazzling 262K-colour display, which makes 65k colour displays look like the SBS test pattern by comparison.

Like the Sony Ericsson Z800i we played with last year, the Z510 features a 1.3 megapixel swivelling camera built into the clamshell hinge. Unlike the Z800i however, the camera does not automatically flip vertically when rotated inwards. This quirk puzzled us for several days, during which we took several awkward upside-down photos that, in an unintentional homage to Mr. Squiggle, had to be rotated to be deciphered. We even pondered whether the upside-down factor was a deliberate ploy by Samsung, intending to crack down on the number of vanity shots being taken throughout the world. After a Google search however, we finally discovered that pressing the volume button in camera mode fixes the problem. This function is sneakily hidden in the back of the manual -- perhaps a lesson in the merits of reading the user guide thoroughly before getting mad at a phone.

For the non-business user, the 138MB of embedded memory should be ample for a collection of MP3s, the odd download and a few folders of photos and video clips. Heavier users with a desire to use the Z510 to view substantial PDF documents and store e-mails with attachments may find the memory capacity limiting, especially given the lack of an expandable memory card slot.

Performance
The short battery life of 3G phones can be a bit of a shock for those making the switch from 2 or 2.5G. We found that with moderate Web browsing and phone calls, the Z510 lasted between two and three days before needing a jolt of electricity.

We were a little surprised at the camera being only 1.3 megapixels, given that last year's D600 featured a 2 megapixel version. Snapshots taken at high resolution looked very pretty on the phone display, but not so impressive when transferred to a PC. As with a lot of camera phones, using the flash resulted in slightly grainy snaps, and photos were best taken in daylight.

The Samsung PC Studio software package was a cinch to use, with the drag-and-drop interface making contact synchronising and file management (via USB or Bluetooth) quick and painless. However, it's worth noting that the USB driver should be installed before the rest of the applications to make sure that your computer recognises the Z510 automatically.

The Picsel Viewer application which made PDF documents so mobile-friendly in our Z800i review makes a welcome return in this model, although Excel files were a little difficult to read.

Web browsing was surprisingly easy, with fast downloads and a simple method for text-field character entry. The only downside was having to scroll through long documents using the flat navigational key - a process none too ergonomically friendly on the poor old thumbs.

All up we were very keen on the Z510, which, with its sleek black look and combination of multimedia and business-focused applications, is cleverly designed to suit males and females of both the fashion-forward and corporate persuasions. Although we were initially judgmental regarding the derivative design, the phone impressed us enough to appreciate it on its own merits, which are thankfully plentiful.
