Hi Paul,
More capable than GNU ? How ?  We've been using GNU ARM in one our
products (similar to yours I think) for over a year and we're impressed.
Once you have an IDE on top, its pretty much plug&play for Windows
users. Code generation is good and its very stable (we/our customers
found very few code generation bugs, the most notable being when using
the "interrupt keyword"). Our guesstimate is that it is within 5% of the
code size capabilities of the big guys (ARM ARM, GHS, IAR, etc). As for
Hi-Tech, my experience in the past has been good with their command line
tools (8/16-bit), however, my experience with Java front-ends (not
Hi-Tech's) has not. Some other tool companies have tried this approach
and have suffered from performance and mysterious VM crashes ("write
once, test everywhere").
 
It will of course take time for the new Hi-Tech ARM tools to "mature" to
the level of GNU. Note that Keil also plan to bring out their own native
compiler next year making the ARM market super competitive from a
compiler vendors pov (I can think of ~10 vendors).

I tried Hi-Tech's offering for MSP430 (of course).  I must admit that I
was disappointed with it (code generation below par, horrible IDE), so
no competition to us.  If the ARM tools are the same, as I expect they
are, I think they're overpriced and not of sufficient quality.

I think our approach is right.  However, we're considering replacing GCC
with something a bit more capable.  That may change as there are things
afoot in the ARM world.
