There's also multiple smaller downtown labyrinths in downtown Riyadh, and 'computer souks' across the middle east. The first time I went to these places I was amazed and bought some really odd electronics (I bought a GSM jammer in Riyadh) but when I was back earlier this year I noticed that all of the wacky stuff was available on the Internet.
I ended up buying it because Saudis bring mobiles into meetings. This would make a 10 minute meeting about an hour and a half long because a senior manager gets and takes a lot of calls, except when I'm in the meeting.
