I have had Linux (Dapper Drake) running on a secondary computer on my desktop for about six months and since I was impressed by it's own complete installation and complete interoperability with all the others I am irritated by my inability to decompress zip files.
I am not particularly thick in computer matters and the fact that I have yet to get AVG working is annoying me.
I guess I am too conditioned my Windows to think outside the usual box but I'll get there and save a fortune.
Meanwhile I still soldier on with XP Pro on the main machine.
But I use Virtual Machines which gives me an extra network to play with, so I am using at present:
Windows 3.11
Windows 95
Windows 98 SE
Windows 2000
Windows XP Pro
Windows 2003 Server
Windows Vista Ultimate
Linux Dapper Drake
IBM PS2
DOS 6,0
Unix
BBC B
MAC OS X
on just three machines. and nine hard drives
