A few general pc/laptop/broadband questions?

a few things (i am not very pc minded!) that maybe anybody could help clear up for me - some may seem very obvious but i know nothing about this sort of thing, so bear with me! 1.) can i run wireless broadband to my pc and my laptop from the one subscription? 2.) has vista sorted itself out yet - is there any nice reviews? 3.) has anyone an opinion on the ei system laptops (cheapies) ? 4.) i am going to get a laptop, a cheap one (less than £400) as i want it for writing my novel on the move/outside watching kids in garden/in bed etc., for taking and showing prospective clients mock ups of artwork on print artist, listening to a bit of music, etc, looking at a bit of internet - nothing strenuous or deman ding - which laptop do you think? anybody please look at pc world - will a ei 4115 do me or should i stop being swayed by the free cover?! 6.) if my bro has changed from bt to sky br/band why can he still use his old email address, or do you keep that? ta!
Answer
You can run more than one broadbadn computer is you put in a wireless router and your computers can handle wireless. for laptop try toshiba or dell. we still run a four year old dell (a little upgraded) and it is fireproof.. i changed a toshiba. also fireproof for an acer which i ran perfectly for a year before i changed to another upgraded acer. you pays your money and makes your choice. remember the makers name is not every thing. models within a range can be lemons.
