6 Clicks. Either a) you can't count or b) you're referring to keeping the keys pressed for a ~2 seconds to directly jump to the phonebook (how intuitive)...
I can only double that. The t68i is the 4th GSM phone I am using and it's the first and last Sony Ericsson.
Speed quality is ridiculous. My previous phone, a Siemens SL45 (which I replaced because I've dropped it once too many times) had crystal clear reception in place where the speech quality on the t68i is just barely tolerable. I am not sure that the lack of speech quality is related to a bad overall reception though; the phone usually picks up signals just fine.
The user interface just sucks. Simple things such as selecting an entry in the phonebook and placing calls requires "CLICK", "CLICK", "CLICK", "CLICK", "CLICK", "CLICK".....
Why not use DNS Resource Records to route lookups for the phone user@domain to the appropriate directory server (aka Call Manager)?
Also, I can't wait to "access Internet services through a telephone keypad"...

Do you have any proof that the Schlumberger chips (which are likely being used on these cards) have been compromised during the 5-6 years of general deployment?
True, but compromising the secret key to program cards at will is likely going t
o cost x times more than $100.
Copying exiting information (which the original author of the thread referred to
) is different from programming a card with new information that must be cryptog
raphically signed correctly. Also, duplicated cards could be easily detected by
embedding a signed ID onto the card.

Short answer: It's not as easy as you may think.
The cash amount is stored in a tamper-resistant smartcard. You'll either need an appropriate key to unlock the card and make transactions (by means of a well defined protocol) or you need to use attacks against the smartcard hardware (power analysis, laser cutting or other). All of the attacks will cost you more than can be gained from the monetary value on the card.
After all, that's what security is all about. The security does not need to be near perfect. You make the attack more expensive than what can be potentially gained from a compromised card. With maximum values up to ~US$ 100 stored on the card, appropriate protection mechanisms are rather easy to implement.
Many European Countries have a similar plastic cash system since many years. The cash chip just had its 5th anniversary in Switzerland, where I live.
These chips are particularly suitable for the payment of small amounts. I frequently use it to pay such things as parking meters; one usually doesn't have enough coins in the pocket when they're most needed anyway. All parking meters, most bakeries and newsstands are equipped with cash chip readers.
The chip is found on all EC and Postcards. This basically means that all debit cards (and I think a few credit cards) have this cash-on-chip functionality.
