Sony Ericsson has released a second range of Bluetooth watches, but the major differences are in design, rather than function. The MBW-150 Music Edition is part of one of three models in the new range of watches that wirelessly synchronise with your mobile phone to alert you of incoming calls and messages.

The new range aims to suit all styles and tastes, and the Music Edition features a large, round face with a black, rubber band. Aside from the bright orange music keys on the left side of the watch, there is no other indication that this is an electronic device, so it can be easily worn without being connected to your phone.

Towards the bottom of the face lies an OLED display. A bright orange backlight notifies you when your phone rings, as well as when you receive an SMS or MMS message. If the caller is stored in your phonebook, the MBW-150 displays the name; if not, then just the number is displayed. When a new message is received, a small message icon appears on the display. Unfortunately, you can't actually read your message on the MBW-150 -- it certainly would have been extremely practical for the message to scroll across the display. Conveniently, the watch vibrates when notifications appear, although this function can be turned off if you wish.

Sporting a glossy, mirror-like surface with a disappearing external display, the Sony Ericsson Z750i looks almost identical to the Z610i. This HSDPA-capable handset is exclusive to Telstra's Next G network and is one of a handful of Telstra handsets bearing the 'Blue Tick' for recommended coverage in rural areas of Australia.

The Z750i offers above average voice quality and decent volume levels. Of course, it offers full access to the BigPond content portal, including the Foxtel Mobile TV service and WhereIs Navigator. Speeds are reasonable for a HSDPA phone, though the display isn't really recommended for long viewing; it's a little small for watching video.

The outstanding aesthetic feature of the Z750i is the external OLED display. Virtually invisible when not in operation due to the reflective, mirror surface, the display only appears when you receive a new message, call or calendar notification. Although the surface is a fingerprint magnet, it's quite effective. The curved edging means the phone slides easily into a pocket, but the flip mechanism isn't spring operated and doesn't feel smooth. Inside, the keyboard and controls are excellent with the five-way navigational pad bearing the grunt of the work.

A study by leading independent UK mobile pricing analyst Pure Pricing yesterday revealed that 3 of the UK's new Business tariffs top all of their business Monthly Indicators. The 3 Business packages take number one position in all six user scenarios, which are designed to independently analyse operator offerings to businesses.

Additionally, the research shows that for the first time ever the new Business Mix and Match tariffs allow people making 400 monthly minutes of calls to pay less for 18 months of use than for 12. The lowest cost for a user making 400 minutes of calls per month on a 12 month contract is GBP306 on 3 Business 600; however, on an 18 month 3 Business Mix & Match 300 contract the total cost is GBP230, a 25% cost saving.

3's new Business Mix and Match tariffs also mean that an individual using 400 minutes per month over a 24 month life can save GBP205, or 40%, on the nearest competitor.

The Pure Pricing Monthly Indicator research is calculated for six different business user scenarios which vary the number of users on the account, total usage and the customer life. The research takes into account a single person using 400 minutes per month and five people using 2000 minutes.

Jo Lynch, director of Pure Pricing said, "Our Monthly Indicators try to provide as independent as possible overview of the market, allowing for a simple breakdown of what each operator is offering UK consumers. Recently we have seen an increase in pricing activity from the UK operators within the business segment, which is generally leading to both increased value and price reductions for small businesses. 3's new business tariffs are a good example of this."

Motorola's Vegas VE20 clamshell has slipped through the FCC, on a straight path to Sprint. The handset comes in a silver color scheme and it reminds of the RAZR and KRZR.

The Vegas VE20 features a 2 megapixel camera with no flash with a microSD card slot for memory expansion and below the screen, there seems to be touch sensitive keys, meaning the typical rewind, play/pause and fast forward.
