Comments on: New Features in Palm OS 4.0 and the m50x Series
- Most expansion devices are secondary storage, and provide a traditional filesystem storage
- Secondary storage: not like built in databases
- Different physical characteristics, so different API
- Pretty similar user experience
- Palm OS apps are copied into main RAM when running (just like on a desktop), and are automatically removed when they quit

RE: Previous Palm Applications?
RE: Previous Palm Applications? and NO 16-bit Color!
RE: Previous Palm Applications?
The IIIC's hardware can only display 8 bit.

RE: Previous Palm Applications?
Sorry for the somewhat brief previous post about what the new Palm OS 4 can handle.
Palm OS 4.0 will handle any program that will run Palm OS 3.5. That is to say that if someone's program that was written for any prior version to 3.5 that worked in 3.5 will work in 4.0.
If the program doesn't work in 3.5, then it certainly won't work in 4.0.
Also, 4.0 will actually have support for 24-bit color (roughly 16.7 million colors), but the hardware will have to support 24-bit color. The hardware in the Palm IIIc wasnot designed to handle 24-bit color.
I hope this helps clear up some confusion. Please feel free to ask me any questions, and I will try to asnswer them.

upgrade to os4. AND I really do need those extra spaces so I went back to 3.5.
RE: Previous Palm Applications?
RE: Previous Palm Applications?
2) os 4.0 is being released like XP is. its coming on new models (very new models), and will be available to actually buy later. of course, its already out on the internet, just do some searching

RE: source?
I figured that if no one was going to post this information, then no one must apparently know that all this information is 'freely' available!
Remember, this is the WWW, and you can find almost anything if you just look
One would be surprised at what could be found on the web if one only looked.

Anxiously awaiting builds so I can use 4.0 on my IIIc and Vx.
I heard Kyocera is already working on 4.0 for their smartphone.

RE: External Memory
Adapting a reader type application to read directly from the VirtualFileSystem is easy, in fact I'm almost able to do it from scratch and I'm a complete amateur at Palm development. I have no doubt that the "name-brand" reader applications will be updated with native expansion support in the days leading up to the release of PalmOS 4.
Kudos to Palm on the nice API design, I think people will adapt very quickly to expansion. Real expansion on the Palm platform has been a long time in coming! :)
RE: External Memory
If not, it's just as bad as the CLIE!
RE: External Memory
You do not have to copy everything into RAM to read a database at all. Every decent app will be updated to support expansion. It is just a few lines of code for basic integration.
If they were to take the TRG route and hack together expansion rather than make it an integral part, what motivation would developers have to move from their current ways to a real expansion/filesystem?
I think Palm is making the right decision, it is about time we get something that the PocketPCs have had for a long time.
RE: External Memory
RE: External Memory
You would never even have to copy the DB over to ram if you didn't want to.
Now one thing I do am /not/ sure about is whether the new PalmOS4 expansion routines apply strictly to their SD slots, or whether Sony is going to adapt them to memory stick.
RE: External Memory
RE: External Memory
Is it enough to notice or care? Probably not. The SD setup has plenty of bandwidth.
I look and see the people bragging about their PocketPCs with 32megs of memory. In comparison, I usually have the same amount of information- if not more- stored in my Palm apps with my 8meg. Imagine a 32meg card in a Palm. How much information is that? It blows my mind...
RE: External Memory
Does the SD slot actually sustain anywhere close to the 10MB/ sec data transfer rate listed? If so, I agree that there will be no problems with storing DBs off of main RAM. Thanks for all of the great feedback.
Dave
RE: External Memory
RE: External Memory
Regarding the SD transfer rate, I'm not concerned because, compared to the competition...
The PocketPCs manipulate data just fine across CompactFlash which is less bandwidth than SD, besides the fact that most PocketPC databases are larger.
So unless Palm or SD manufacturers completely screw up, we should finally have a usable expansion standard.
RE: External Memory
If what I have read above about the new use of SD -- seamless, like Pocket PC -- is true, Palm will clearly have saved its ass from being kicked/gobbled/beaten by Pocket PC! They will have grabbed the year they need to survive until the intro of their ARM units in 2002.
This is very exciting and I cannot wait to see the m505 and the new PalmOS 4'ed CLIE!

Palm running scared?
RE: Palm running scared?
Ofcourse! RE: Palm running scared?
but those new features on OS 4.0 will nuturalize that.

RE: Palm running scared?
Given the growing overhead costs of Palms inner imperium, it may be even convenient to them that others develop the platform further and they remain like a retired in Miamy with there monthly paycheck and their Porsches. And still play the "I am the master of the PDA universe" game.
Even thought the Palm OS developer was the nowadays Handspring CO.
I suspect that true driving force for further developmen will come mostly through Handspring or HandEra.

You don't know what you're talking about.
Potential customers are starting to become sophisticated enough to see through their smoke and mirrors act, so I doubt Palm is going to still be able to sell PDAs at a premium just because they look nice. (Witness the current m505 screen fiasco.)
If you want to learn something about Palm's current and future problems, read this article:
No Corkscrew?
but for the exectuive edition, can't they at least
have the option for a corkscrew?
...
Where should I go to beta test the new OS?
Card Info app?!
RE: Card Info app?!
However, if you look at PalmSource material, you will learn that cards will actually support subdirectories and even "autoexec" features, and that the API allows the creation of some kind of Explorer.
TRGPro & OS4.0 features
I don't think Sony is going to do the same for their Clie as they haven't shown any interest in improving the use of MS in the Clie. What they will do is they will release a Clie2 with features of the Palm M505 but with the MemoryStick slot & running the full OS4.0. If you want OS4.0 features then get the Clie2. Sony is not interested in patching OS4.0 features into their current Clies running PalmOS 3.5.x. The current Clie doesn't have enough FlashROM to accomodate OS4.0.
RE: TRGPro & OS4.0 features
N700C is running at palm os 3.5.X as stated in sony.jp website.
