"Webcam support in Linux has greatly improved very recently. With the merging of the GSPCA and UVC drivers, Linux systems based on recent kernels support most webcams in existence...out of the box.
"Wifi support in the Linux kernel has been, and is being, overhauled. Atheros, a leading manufacturer of Wifi chips, has released source code for much of their hardware. Many of their chips now work with Linux, out of the box, and support is improving rapidly.
"New graphics stack. Many components of Linux's graphics system are being improved, Linux is gaining GEM, a new graphics card memory manager, created by workers at Intel, EXA/UXA, which is a new 2D acceleration system, DRI2, an improved version of the Direct Rendering Infrastructure. ATI has been releasing code for their chips, which will greatly aid creation of open drivers. Hopefully other companies will do this as well."
