Lpc2000

I'm just getting started with the ARM processor (just reading--no 
hardware yet) and found the LPC chips.  At first they seemed to be 
great but after looking into the data I'm having second thoughts.  
Are these chips ready or still in a beta stage?  There seems to be 
problems with JTAG loading the flash memory.  Has this been 
resolved?  Can GCC and the Wiggler JTAG interface be used to debug 
applications in flash with the LPC's?  Are there any 'show stopper' 
issues with using these chips in a commercial application?  I'm 
still reading through my ARM manual (ARM System-on-Chip Architecture 
(2nd Edition)) so I'm still climbing the learning curve.

TIA
