+1 for bluefin. I'm actually running that on my own laptop. Fw13, it's been rock solid, which is exactly what I wanted.

KDE is genuinely incredibly flexible - you can make it into pretty much any GUI that exists. The default windows like set up is fine, but there are so many easy tweaks and changes you can make to get it however you want. I have a floating dock-like set up instead of a window-like taskbar, with application launcher, icon-only view, system tray, clock and power button.

For simple tweaks yoy can right click on most component of your KDE panels and select "Show alternatives..." to see different official versions of the same component. For example, the Application Launcher offers an alternative Application Menu with cascading menus like an old-school windows start menu, or a full screen gnome-like Application Dashboard. And there are also loads more user made tools if you right click and select "Add or Manage widgets". Every component of the desktop is a widget and can be moved, swapped out, duplicated or replaced.

Xfce and themetwister get you near exact for mac os or windows visual clones.

You can also just hook your phone up via usb and enable usb tethering, allowing the PC to use wifi or mobile broadband via the phone.

For reference, sharing your local IP address is a little like saying “I’m in room 223” (local IP address) and not saying what building (network) you’re in. Someone can’t walk into 223 in a different building and get to the same room you’re in.

Honestly, even if someone knew what network you were on, a local IP address wouldn’t be that useful because even if they successfully got on your network, as long as you have a properly-configured firewall and no vulnerable network-exposed services on your system, they can’t really do anything.

Honestly, while it’s still not a bright idea to tempt fate like that, even sharing your public IP isn’t that bad for the same reasons if it’s a competent home user; the worst that can happen on a properly-configured network is that someone tries and fails to exploit vulnerabilities that aren’t there and MAYBE drum up your internet bill. Also, for most ISPs, your public IP changes pretty often anyway, usually something like every few days to a week, due to changing DHCP leases.

I think there's probably a ~~raccoon~~ guy up near Boston who could use that toothbrush.
