If you notice Martyn's latest post there have been quality recorders 
available for a while. There will always be something new, but I don't 
go along with the "serious limitations". The current marantz does a good 
job, is a quality recorder, Nagra has a good HD recorder and so on.

What I see is making the transfer speed the primary criterion. I've seen 
very little interest in the sound quality these things may or may not 
have. The primary thing about a recorder is that sound quality. Why do 
we see endless posts eager about transfer speed, but far less on sound 
quality, battery life, case and control durability, and so on? I don't 
think I've seen a single one of these posts that talked about the 
display metering.

With MD's, users talked of nothing but size, battery life and capacity. 
So manufacturers responded with ever smaller recorders, removing 
connectors like line outs to make them even smaller. And with greater 
compression that turned out poorer sound, but recorded a longer length. 
And energy conservation that made the drive louder. Continual clamor 
about transfer speed may get all sorts of unwanted side effects. Right 
now we are sending a message, intended or not, that sound quality is way 
down our priority list. And metering is totally unimportant. It's not 
way down mine.

On the other hand I do have a fellow biologist who did just drop one in 
a mudpuddle, a pretty clean mudpuddle of fresh rainwater. Cleaned and 
dried according to all the advice it was dead, permanently. And some 
very hard to replace documentation photos with it. I have no idea yet 
how often they will die vs how often they will survive, and want to 
know. The same for all kinds of other hazards. This will not be info we 
will get out of company AD men. Nor will the experience with digital 
cameras totally tell us.

I've been following them for some time. Eventually my digital camera 
will be abandoned by the software and I'll have to replace it long 
before it's worn out, only a few thousands of photos taken, moving from 
a camera that I use PCMCIA Type III hard disks to the solid state ones, 
seemingly all that's available now. I've paid particular attention to 
the experiences of fellow field biologists. Let's just say that the 
durability of this media is not absolute, it can and does fail. 
Sometimes in simple ways that are hard to believe. Yes, the lifetime 
warranty replaces them, but not what's on them.

I've been with computers for a long time. In that time I've lost lots of 
money when what I was using was abandoned. That digital camera I mention 
above cost over $5000 when I bought it, I have mechanical film cameras 
that work fine and are 30-40 years old, which spreads the initial cost 
over a much longer life. No way I'll get to spread the cost of the 
digital over near as long a time period. Right now, the investment it 
would take to replace it is also not trivial, this is a SLR digital with 
interchangable lenses and flash equipment. I'd have to change brands, 
compromise on functionality, buy a new set of lenses to replace it. The 
closer you tie your equipment to computers the more vulnerable you are.

Part of the solid state equipment being very recent, or even not out is 
that most of the info is straight from company publicity. They are going 
to emphasize all that they can the good points, glossing over as much 
else as they can. To jump in on the basis of company press releases and 
believe that this equipment is the ultimate of perfection is very 
unwise. Real use by real field recordists will tell us in time just 
where these stand in our alternate equipment choices. It's well to look 
beyond the press releases and messages from the company AD department at 
some of the possible worst case scenarios and ask realistically just 
what we will find. I certainly don't want to spend years looking for 
Brimley's Chorus Frog as I did, only to find the only recording I will 
have this year to document it has died. I'm very careful in my equipment 
choices as a result of that. I know from the experience of other field 
workers that solid state can die and am watching to work out my odds, 
before I'm forced to use it. It's probably not as big a issue for 
hobbiest recordists recording relatively easy to find stuff.

I'm not currently in any need of a new recorder. Others are. What would 
various people buy if they had to get a new recorder today, not 
tomorrow, today? You are getting on a plane, going on a long recording 
journey to some ideal area, you are leaving immediately. Some of what 
you record you will get one take. The area provides sound recording 
opportunities of the highest quality. You have no recorder, what will 
you buy? I constantly keep in the back of my mind on many types of 
equipment this very question. It could occur if my current equipment was 
damaged beyond repair. What I would get changes with time, it's rarely 
something that's just out with entirely new technology for that use. For 
me it would not yet be a solid state recorder, too many unknowns and 
risks for this conservative old geezer.
