I posted a review of Outlook Web Access (or OWA) on my blog (http://admira.wordpress.com/2007/10/...ternet-tablet/)

I won't put it all here but the long and the short of it is that the two browser engines (MicroB and Opera) actually look very different. I have screenshots on my blog so feel free to have a look.

Personally I prefer the Opera rendering of OWA.

I hope that helps someone out there!
