I am about to get an Inspiron 8600 and wonder if I should get the TM 1300, which supports 802.11b/g, or the TM 1400, which supports 802.11a/b/g? I currently only have access to 802.11b and 802.11g networks, btw. I wonder if I should still get the TM 1400 just in case? Will 802.11a be more widely available in the future? Do the TM 1300 and the TM 1400 perform identically in 802.11b and 802.11g networks? Which card should I get? Thanks for your help.
