Quote from Bolimomo:
I am using a HP dv9730us laptop (running Vista) as my primary trading computer. Bought at Fry's for about $800 in March 2008. I like it in general but this laptop had been sent back to manufacturer twice for repair. hard drive problems and motherboard problems. So I am not that confident in HP laptops now.
I also bought another Compaq laptop (still using the Compaq brand name) at about the same time and so far no issue. This one was at a lower price even (about $550 on sale at the time). HP owns Compaq (I thought they don't use the Compaq brand name any more...).
Whenever I travel, I bring both laptops plus 2 external 19-inch or 20-inch LCD monitors to trade from the hotel room. With wi-fi commonly available these days, it's quite convenient. I bring along a LAN switch too in case there is only a landline high-speed internet in the room available. I will share that connection between the 2 laptops.
I suggest that you buy a laptop that supports an external monitor (look for the SVGA outlet on the laptop, usually on the side), and bring an extra monitor with you.
Vista versus XP: I have no problem using Vista only. Perhaps it depends on your trading platform.
My travel tips: When using wi-fi, not all rooms are equal in getting strong signals. Talk to the hotel receptionists to see if they can put you in a room that is closer to the wi-fi routers (they sometimes know based on guest complaints). After checking in the room: test the wi-fi connection before unwinding. Because comes 6:30 am/9:30 am the next morning it is not the time to learn that the wi-fi is only half-working. Bring some extras: power strings, RJ45 cables, mouse, power cords, etc..
