Hi,
The air card i bought, GPRS, fitted into a slot on the left side, of my laptop. Not USB skt.. Aerial detachable, about 3 inchs long, card width 2.5 inchs, length 3.5 inchs. Did not know slot was there untill i was shown it. Card does not potrude. Speed was not as good as phone line, to be expected. instead of one min with phone line connection, it took 2 mins, for photos and all, except videos, O.K. for me. Did not try downloading videos. Always get big downloads at night, at home, when i was sleeping. My L/T has a Athlon 64, 3600 chip from 2004. So not to fast. You can get a promg. that will compress your photos, files and videos if you want. and will speed up your downloads when using GRPS. on a laptop. Can get a free 30 days trial. Have not got address to hand, will have to look for it.
According to the book I got when i got the aircard. If you have win. lower than XP you will need a firewall, can be got free at

Your P.C. is not locked to a single network and can be used world wide. So if travelling seek out the cheapest network and buy a SIM's card for that and insert it. The cheapest rates i got in LOS in 2005 was 0.06B a min.
Did not see any difference in connection speeds, indoors or outdoors. Used this in LOS.from south to north and in bordering countries. Everywhere in LOS was very good.
As i say, maybe not the cheapest, but i think the best. Rick proves my point with the problems with his 1100B one. You get better reception outside. Lot of rain this morning. With a decent aerial, and the one i have got, reception is the same indoors, or out. Even in areas like BKK. in the middle of a hotel. You get what you pay for. As with everything in life.
Being able to use it worldwide and other things made it O.K. for me. Even though i don't travel as much anymore.
