Admittedly, the install process is an ever more baroque complex "kludge" 
of work-arounds now that Windows 7 is becoming the prevalent operating 
system, and I live in dread of the future Precision Mapping release that 
will finally break UIview's PMap Server. 

However, UIview is still a much more open and extensible system than 
other APRS apps.   It's documented API (applications programming 
interface) allows add-ons to continue to be developed.   It's symbol set 
can be updated since it is stored in external BMP graphics files. 

At the time it "died" five years ago, it was so far ahead of any other 
APRS app in features and capabilities due to the vision and imagination 
of it's author, that it is STILL the most comprehensive and functional 
APRS app.  It is still the only one with a "commercial grade" built-in 
help system.   It is the only one that can use current zoomable vector 
maps without being tethered to the Internet (except for APRSpoint which 
requires the expensive Microsoft MapPoint to function).

I am distinctly underwhelmed by Xastir.  The fundamental problem is that 
there is simply NOTHING in the Linux world equivalent to Delorme Street 
Atlas, Precision Mapping or MapPoint; i.e. a ready-to-use compact vector 
mapping system with current data.   Despite Xastir's claim to work with 
"hundreds of map formats", they are all either obscure specialized 
bitmap formats that require TERABYTES of hard disk space to cache static 
images at varying resolutions on a local hard disk, or high-end 
professional GIS vector formats like ArcView  for which comprehensive 
data is not available to the average amateur. 

AGWtracker looks promising but it also is hostage to the Internet if you 
want high quality maps.  

Background:  I consider being able to operate without an Internet 
connection critical, since I run a mobile APRS installation with a 
laptop display, and want to be free to travel cross-country with a 
fully-scrollable zoomable real-time mapping display.    It is very 
frustrating that NO   APRS app can do this other than UIview and 

[While APRSpoint is more-or-less currently supported (though there are 
intervals of 9 months or more between updates) and supports high-quality 
vector maps from MapPoint,  it is so lacking in features (no digipeater 
functions, no KISS support, no igate capability, no proper overlay 
support), that it is really no competition to the "dead" UIview.]

One shouldn't be helping newbies to adopt a completely dead, 
non-updateable app that can't even display current symbols.    [I am 
giving an APRS presentation next week to a radio club on the high desert 
north of L.A. (Victorville) and will be live-demonstrating basic 
trackers, full two-way messaging mobile setups and complete home station 
setups.  I will be advocating UIview, APRSpoint and Internet displays 
for these systems.]

Does MacAPRS even work correctly in System X?  I thought it was bound to 
the classic pre-Intel Mac OS, but I'm not sure. 

On the Windows side, WinAPRS is going to be a total headache going 
forward.   WinAPRS was cross-compiled from the Mac version with a tool 
that spits out 16-bit Windows code (i.e. Windows 3.x!!!).  Among other 
things, this is why WinAPRS only supports the first four com ports.     

Until now, this hasn't been much of an issue.  The 32-bit OSs starting 
with Windows 95 up to XP incorporated a 16-bit subsystem a.k.a. "WoW" 
(Windows On Windows) that allowed 16-bit Win 3.x code to continue to run 
to run on these newer flavors of Windows.  

Vista and Win7 quietly dropped the WOW subsystem (in the interest of 
stability and security), meaning ANY program containing 16-bit code (a 
surprising number of "32-bit" programs contain bits and pieces of 16-bit 
code recycled from their Win 3.x predecessors.) are now hopelessly 
broken, unless you want to install a virtual machine running XP inside 
your new Win 7 setup.   This applies to both the 32- and 64-bit versions 
of both Vista and Win 7.
