My 8703e has rebooted twice, maybe 3 times, since I got it in April. Once I remember I had tried to open a web page that is really large and I thought that's what caused it. The other time I had no idea what caused it. I've noticed since upgrading the OS that I can view web pages that it choked on before. 8703user, maybe try setting your browser emulation to something different and see if it helps.
