WIRELESS:Do not buy—802.11b: .Maybe buy—802.11g: “g” is faster than “b,” But it’s about to be supplanted by “n.”Do buy—802.11 pre-n: There is some risk with this as the n standard is still developing.
MONITORS:Do not buy—CRTs: Those are the huge heavy old TV style monitors.Maybe buy—large-screen CRT HDTVs: .Do buy—LCD TVs and plasma displays: They’re thin, gorgeous, and expensive.
STORAGE:Do not buy—another ten-pack of 3.5-inch floppy disks: .Maybe buy—CD-R discs: Writable CDs are super cheap and hold roughly 700MB of data..Do buy—thumb-sized flash drives: Definitely one of my favorite inventions of the last ten years.
