PDAs, Cellphones, Wireless Because of this whole Easter thing, news is kind of slow today. So, yes, we are going to talk about a charger and a rumoured release date for the Palm Pre. The Palm Touchstone is a charger that uses magnets to keep the phone in place, while charging it through induction; there's no plugs or anything. Palm has let out more details on this new type of charger, and there have also been a number of hints that the Pre might be released on Queen's Day (April 30 for all of our non-Dutch readers).

It's Electromagnetic induction: http://en.wikipedia.org/wiki/Electrostatic_induction

Also, please don't feel bad about getting this wrong. To quote Wikipedia:

Electrostatic induction should not be confused with electromagnetic induction; both are often referred to as 'induction'.

yup. It's nothing that great...all it is is a loosely coupled transformer(i.e. two electromagnets). The only major trick here is compensating for losses due to loose coupling (as opposed to a transformer where the two cores are directly in contact and are geometrically symmetrical, thus fewer losses in magnetic flux)...

This rumored 4/30 launch date conflicts with engadget.com's findings. Everything is speculation at this point, so its impossible to know what to believe. Seems there is no doubt this will occur in the next month or two though.

Didn't realize the Netherlands still had a royal family. I thought it was an autonomous collective.

Induction efficieny

How efficient is induction? It would be a shame if millions of phones started using this simply because it was "cool". Longer charge times, more fossil fuels burnt. Sounds like a big negative to me.

It is efficient enough...though not as efficient as plugging it into a socket. With the right contact surfaces (and geometries) and some clever signal processing you can get it so losses are negligible. Systems such as these are already used in industry when there are hazardous environments where having an electrical connection would be too dangerous (in underwater situations unfeasible).

I jumped over and had a look a the Palm Pre page - looks like a nice phone, the disappointing thing is the small size of flash that is included and there is no mention as to whether it is possible to expand storage using some sort of flash card.

The one thing that has been holding me back from an iPhone or an iPod touch (or any other smart phone) has been the lack of storage; I have 50GB worth of music and would like to store all of it on the device at once - the problem is that there isn't a phone out there with either sufficient storage by default or the ability to expand out to that size. If there was a 32GB model and a mini-sd slot (so I can put a 32GB card in it) - I would purchase it instantly but so far from what I have seen it has no expansion which is kind of disappointing.

Do you really need to carry around all 12,000+ songs at once?

I don't feel the need to load and unload songs on all the time - I'd prefer to load them all on at once and have them all with me so as my mood changes through the day I'll have all my music at my finger tips.

But the problem is that I've been in a situation where a song I haven't listened to in months - I suddenly feel like listening to it. What ever the excuse maybe it doesn't excuse phone companies from failing to provide sufficient space or at least some form of expansion that allows those who want a lot more space.

Making up excuses or trying to convince me that I don't need to carry around 50GB of music doesn't change the fact that I have a demand from a product I am interested in and no one has stepped up and met that demand.

yeah, I wish they'd start sticking dual MicroSDHC slots in phones. its not like they take up gobs of space. fit them under the battery or something.

Sounds like a hard-drive based MP3 player is what you'd need at the moment... trouble is none of them are phones, obviously. I get where you're coming from, I've got about as much music as you do and I'd love to carry it all around with me on a flash-based device.
