I've been waiting for months for there to be a PDA that uses Palm OS 6, a.k.a. Cobalt. That (latest) version of the operating system is faster than older versions, lets more things happen in the background, and has support for more hardware features built in. It was released months ago, and the rumor sites suggested that PDAs released this fall would probably use it.
Cobalt version 6.1 was released recently, adding more cool stuff, which was a little annoying, 'cause presumably it'll be months longer before there are PDAs that use that version. But meanwhile the rumor sites had been saying that PalmOne (the company formerly known as Palm recently split into a hardware company, PalmOne, and a software company, PalmSource) was coming out with a new PDA any minute now, and it was sure to run Cobalt 6.0.
Yesterday, PalmOne announced the Tungsten T5, to be available in a month. It has many big advantages over my current Palm M500: 320x480-pixel color screen instead of the 160x160 black-and-white screen I've got, 256MB of memory instead of the 8MB I've got (and it's special memory that doesn't go away when the handheld's battery dies, which would be a huge plus; I've lost data that way more than once, despite regular backups), much much faster (400MHz processor instead of the 33MHz processor I've got), and various nifty new features that add new capabilities.
On the down side, the case of the T5 is plastic (the M500's case is metal on the front, plastic on the back); I'm not sure I'll be able to tell, but I think I will, and I think I won't like it as much. And the T5 runs Palm OS 5.4, a.k.a. Garnet—which is better than what I've got, but not as good as Cobalt. (And PDAs, unlike computers, generally can't be upgraded when major new versions of the operating system come out.) Also, the T5 is apparently noticeably thicker than the M500; one of the best things about the M500 is how thin it is.
I'll probably end up getting a T5 anyway; I've been pretty dissatisfied with various things about the M500 lately, and I've been itchin' for a new gadget. And who knows how long it'll be before Palm comes out with a PDA that runs Cobalt.
Still, a little disappointing.
