I went to newegg.com and bought a few things I needed:

1)[color=#FF9900]D-Link DI-524 IEEE 802.11b/g, 802.3 Wireless Router[/color]
I need this to connect my PSP to the internet via WiFi. I also need the router to connect both, my Xbox360 and my PC, via ethernet cables. And this $43 wireless router got good reviews at newegg so I decided to get it.

2) [color=#FF9900]GENERIC 10X5-827HD (Orange) 100 FT Cat 5E Orange Cat 5e 350Mhz Network Cable, Orange[/color]
The router will be sitting next to my PC but far away from my Xbox360 and i'm not going to spend $100 on a WiFi adapter so I purchased this 100ft long ethernet cable for $8 to connect my Xbox360 directly to the router. Besides... wired connections are more stable and have no interferences and other things that may cause lag in games.

3) A digital camera (can't find the link now)
I also purchased a cheap digital camera so that I can take pictures and post them online and etc. In the past I used my cell phone camera but I am no longer subscribed to the multimedia features, so I can't do that anymore.
