The Wifi was OK. The access occasionally timed out, 
requiring reclicking on access proxy. 
Bandwidth was OK, we downloaded much for installation per

Resize a Windows (NTFS) partition to be smaller.

Be sure to back up one's data before screwing around with partitioning.
Then install Linux in free space. 

Try Linux without disturbing existing Windows installation, 
by using a live CD.  Great for playing with Linux or Python without 
installing on the computer.  Great for forensics and system recovery also. 
Great for trying a Linux distro before installing it.

    boot: knoppix no3d noswap

The noswap option is important for not accidentally modifying the hard drive. 
Many linux disks can be used as live CD/DVDs.
