Network Mac's reliably. Um.. Yes. Can you get an I.P. address?
Solaris apps and GUI, how many thousands is enough? If you want something like Outlook there is Zimbra and it works on Palm OS plus just about any other hand held and it also works with Exchange. If you want a browser there is Firefox but then you would have already known that since IE is DIEing. If you want word there is openoffice which will probably outpace MSoffice in a couple of years. Why?, because MS is killing itself with it's licensing and cost. They should do a google search on Auspex.
There are some cool apps that run on the MS platform since it is very common. But, if MS is not careful Lynux will sneak up from behind since it is user friendly, just as stable and less expensive.
