Apparently more than two million people downloaded the Firefox 2.0 browser in the first 24 hours after it was officially released. But if you're not one of them, you're probably wondering whether it's worth getting. Plenty of people on the Web have an opinion, so here's ten that we found most informative. Note, most are aimed at people who are already using a previous version of Firefox.

1. 'Firefox 2.0 is a solid improvement' at Linux.com. "It's not a drastic change from the 1.5 series, but Firefox 2.0 bring enough improvements to make the upgrade worthwhile."

2. 'Mozilla Ships Firefox 2.0... It's a Dud' at Windows IT Pro. "it's a woefully minor improvement over Firefox 1.5 that suffers from various incompatibility problems, especially with themes and other add-ons. I wouldn't recommend this new version, to be honest."

The fellas at Boing Boing are wondering if anybody knows what this robot vehicle sighted in Japan is exactly. Apparently it can climb curbs and stairs, and navigate crowds, so well that the occupant seemed relatively blasé about his robot howdah. (Though the crowd was not so sanguine and often nearly stopped him by pressing around gawking.) Seen in Tokyo by the Yoyogi park entrance - the 'bridge of freaks' according to the report - this past weekend. [GT]

Instead of the same old rubberized black power cable, the Power Aware Cord pulses brighter and brighter as you draw more electricity.  Developed by Anton Gustafsson and Magnus Gyllenswärd for STATIC!, the idea is to draw attention to not only how much power you're using (in hope you'll consume less) but also that simply by seeing the electricity flow, you'll become more aware of your overall relationship with your gadgets.  (The next step is not taking them to couples counselling; they already go without you.)  [GT]

Here's another scanning solution for those of you who like using good old pen and paper for taking your notes and drawing diagrams, but would like an immediate way of capturing them digitally for later editing on your PC.

The DigiMemo A402 is a special pen and board that will capture everything you write in ink in its memory for later transfer to your PC via USB.

It has a built-in 32MB memory which can hold 160 pages of information, and can also use an optional CF card to store up to 999 pages. Its low power consumption allows it to last for over 100 hours of continuous use. Pages can be easily added and deleted on the device. The accompanying software allows viewing, editing and organisation of pages, plus optional handwriting recognition to translate your scribbles into plain text.

Utilizing the electromagnetic technology, it lets you put any ordinary papers on the pad and use the inking pen to write directly on papers. Even the thickness of papers laid on the pad is 12mm; your handwritten notes can still be captured and stored in the memory of DigiMemo.

It costs just £110 from Selwyn Electronnics. Batteries, pens and paper is available from normal stationery stores.

OK, so organising your business cards (you have business cards, right?) isn't the most exciting thing ever, but is necessary and a perfect excuse for a piece of technology to help.

Mini desktop scanners aren't particularly new but version 8 of the CardScan Executive, released last week, is compact and versatile.

It features a sleekly designed desktop scanner with contemporary styling and silver finish. It makes colour scans of business cards in three seconds, and synchronises with Outlook/Outlook Express as well as ACT!, Lotus Notes, GoldMine, PDAs and smart phones.

It comes with CardScan software that can consolidate contact data using drag-and-drop and import, eliminate duplicate records, categorise contacts in multiple ways, and keep data synchronised across devices.

CardScan Executive costs £199. There's also a CardScan Personal version that scans in monochrome (£139)

So, Darth Vader... he's the baddest bad guy in the galaxy eh? How about this video that lifts the lid on his childishness? They never told you that about the dark side did they?

We wrote about the launch of the new N Series of Navman GPS products here a little while ago. And to celebrate the launch, they took me on a trip round London Town to discover all the best bits of these new devices, and particular the built-in cameras for using their Navpix tecnology. Check out the Navman website here for information on stockists. And make sure you watch to the end - you'll be rewarded by some random sighting of a man with an eye patch.
