### Arrow of Time

I've been thinking about the arrow of time, and thermodynamics.

I continue to be uncomfortable with logical positivism, the Copenhagen Doctrine, etc. I still believe that there is a physical reality, even absent the observer.

What if we were actually perceiving multiple universes, multiple histories? As in the many-worlds hypothesis, where reality is constantly forking at every decision point.

"Forking" tends to imply a direction, the arrow of time, and exponential growth.

But what if universes converge as well as diverge? Or, rather, sans the arrow of time, there are multiple states that can be reached by a small change from any given state. If certain of states are considered to be earlier in time, they may be said to converge; if certain are considered to be later in time, they diverge.

What if consciousness, the observer of reality, is actually perceiving many such neighbouring states, averaging them, if you will. Then this averaginging would reflect the most probable neighbouring states. Which is essentially a thermodynamic statement of the arrow of time.

I.e. an observer may be considered to be at a point in this non-arrow-of-time dimensional space. From this point, the observer looks around, and perceives a neighbourhood. of neighbouring states. But normally the observer averages the neighbourhood - and this averaging sucks the observer and observations along in a valley finding, seek the highest probability, manner.

### Back to the Future

What does it say that I, a committed handheld gadget early adopter, now have only a cheap cell phone? And that I am considering adding a separate, cheap, Palm PDA?

I.e. what does it say about the market for handhelds, PDAs, SmartPhones, etc., that I am considering - heck, actually have - and going back to my cell/PDA configuration of more than a decade ago.

My current cell phone is a Motorola V197. Essentially the cheapest cell phone that i could get, unlocked. It has minimal address book functionality, and that's about it.

I don't currently have a PDA, apart from the limited functionality of my cell phone. I was shopping today, and am probably homing in on the Palm Z22 (99\$, "technophobe") or TX (270\$, WiFi).

I am, or at least was, an early adopter. I got a cell phone before they were popular or digital - as a modicum of safety for climbing. I purchased the first Palm PDA.

My wife and I agree that our best cellphone ever was our Kyocera SmartPhone. A good enough phone, and a good enough pen-based PDA. I negotiated two job changes using text messaging and the pen on that phone.

But I have been disappointed since then. My most recent disappointment was my AT&T Tilt (HTC 8925). Now, the device formfactor itself was not a disappointment - but its lack of durability was. A minor fall to a carpetted floor broke the screen. Googling reveals that such problems are common, and that the warranty seldom covers such damage. I am reluctant to replace this rather expensive but apparently unreliable device. Moreover, in at leas one way oit is overkill: I never used the slide out keyboard, at least not after the first day. Pens rule!

Which is probaby the problem: I love the pen interface. I hate the mini-keyboards; and I especially hate the pseudo-keyboards of numeric pad phones. But there are almost no cellphones, bar the HTC family, that have a decent pen interface. An always out keyboard wastes precious screen space.

The iPhone is cool, but Steve Jobs apparently has a thing against pens, since his erstwhile rival promoted the Newton.

I naturally gravitate towards Linux devices such as Nokia's web tablets, but, again, they have no pen interface. Nor do any of the numerous Linux ports to PDAs and SmartPhones appear to support pens.

So, this leaves me with non-phone PDAs, mainly PalmOS and Windows Mobile 5 and 6.

Hence my reversion "back to the future": back to carrying a separate phone and PDA. The only saving grace is that this time around, the PDA may have WiFi or GPS. It's a pity that the PDA won;t be able to dial the phone via bluetooth.
