I run it on a work-provided Centrino 1.6GHz tablet PC under Windows XP
Tablet Edition. One feature of this is there's a virus checker permanently
on, and which I can't switch off (and nor would I want to). This may affect
what I see below:

VRPC sucks CPU. When running with CPU-hungry Windows applications it causes
everything to slow down, rather than just running at a slower ARM speed.
These are probably not a problem if you want a solely RISC OS machine, but
if you're running RISC OS for just the odd application it slows everything
else down to the extent that it's just easier not to run it. What would be
nice is if VRPC could be set to take not more than XX% of CPU so it would
play better with other applications. Particularly when switching between
Windows applications it'll sometimes sit there not redrawing its window,
occasionally up to the point Windows has decided it's crashed.

(I've just been playing with Windows Taskmanager: 'Above normal' priority
seems to help some of these problems)

The mouse pointer support is poor. There are good reasons why
absolute-position pointing devices (like the tablet screen) don't work, but
I'm not talking about that. One is that my mouse pointer is jerky (maybe a
CPU load or virus checker thing, I'm not sure). The other is that my
touchpad only has two buttons. Under Windows there's a function to emulate
a middle click with left+right, but VRPC doesn't pass this through. It
provides a middle or right-click on the Windows Menu key, but on my keyboard
that's 15cm away from the touchpad - not useful. It's poorly configurable
in this respect. Similarly the drivers provide scrolling actions using the
sides of my touchpad, but these aren't accessible under VRPC. It would work
if I had a hardware mouse with three buttons, but I don't want one of those
- my point of having a laptop is I can use it without a desk. I've yet to
find a three button touchpad or trackball that's designed to be used with a
laptop when in knees mode, and have only ever seen one laptop with a 3
button integrated touchpad. RISC OS is very mouse intensive, so a poor
pointing device makes it much less usable.

I've not found a good way to synchronise files with my Risc PC. I want the
same files (programs, Boot sequence, etc) on both machines, and if I change
a file on one machine it to be reflected on the other. The only way I can
make this work is some kind of network share, but NFS is too slow from the
Risc PC. Access is a possibility, but I'd much rather serve the files from
my Linux box where they can be backed up sensibly. The laptop is only on
when it's being used, so it's no use as a fileserver.

VRPC doesn't work under VNC/rdesktop due to its use of DirectDraw (and the
mouse/keyboard input from DirectInput). So I can't run it on another
machine (a desktop machine, for example) and view its display on the laptop,
which would solve some of these issues. It'd also mean I didn't have to
have a hot laptop on my lap all the time because the processing would go on
elsewhere.

The phpBB support forum is terrible: you have to keep checking it to see if
there are any new posts. There aren't many, so there aren't many reasons to
check it, so it might take months for others to read your post.


I should stress that these are the issues /I/ have with VRPC. Other people
might not find them to be issues at all

I had plenty of my own issues with it. But now I almost exclusively use
my Iyonix for RISC OS. Here are my comments:

The thing I was ultimately most annoyed with was the filename handling,
which ironically, is probably the easiest thing of all to fix out of all
of the things Theo and I named.

There's also no USB function at all. No access to the parallel port
except for straight printing, i.e. the Parallel_ SWIs don't work. All
the things that would have made it an option at work, in fact.

Though art no doubt wiser than I where computer matters are concerned, so
I have a question Mr D.

I have VRPC installed on my XP box and from within VRPC I can access the
Pendrive inserted into a USB socket.

Is that not access to a USB function from within VRPC?

I should explained better what I meant, so thanks for pulling me up!

You can access mass storage devices, it's true. But you can't control
a device like a USB radio from RISC OS.

The topic came up for me recently after I'd designed a USB device, and
I was asked to provide a test application for it, to be used by the
production testers. I had written one for RISC OS. Unfortunately
RO is unknown in Israel. They nearly bought an A9Home... unfortunately
again, someone else seems to have stepped in and written a Windoze
test app.

I enquired from Virtual Acorn; there is no USB stack in the product,
neither Simtec nor Castle. You can only access devices via HostFS.

The mouse issue is already a pain in RPCEmu, and I would have thought the
JITed emulation would improve matters. It's a shame it's not the case,
without a good feeling when moving the mouse, the whole RISC OS experience is
spoilt.

Anyway thanks for the comments, it helped making my mind up !
