I have FTP, telnet, ssh, VNC, and a whole lot more on my Palm Treo 650.
Oh yea, can watch just about any kind of video (including Divx variants), read ebooks like PUB LIT and other formats (including PDFs!), can basically install almost any type of software. Only thing I cannot do is access the Novell VPN at work(YEA!) since they don't have a palm version of the software.
Nice!
