...I've been .. using ssh, scp, and web...
You know that -X works just fine with ssh on the N8x0, don't you? That magic parameter allows you to run Xwindows apps on your N8x0 just as you would a larger workstation. I typically pull up nedit, xchat, or various little apps from mine. WELL, "screen" works with them too. No, I didn't know that either. I told a co-worker about my fear of lost scripts this morning, and that screen had saved my arse, and he told me he's been using screen and X on his N800. His connection drops, he reconnects, and his Xwindows are still there?!
Last time I tried it, I couldn't get past thunderbird password prompt. How do you enter text on a remote, non hildonized, app? (with an n800 and no hardware keyboard).
... big PDA systems like the Advantage or Shift from HTC look a lot better for many jobs including cross-platform programming (JAVA)
Maybe you need the wimax tablet, Betty?
