none of you would recomend a netbook?
netbooks are laptops that use intels "atom" processor, its designed for small size and low power consumption. they've been around for a while, you may have heared of the asus "Eee pc", that was the first. the benefits are longer battery life(6 hours) and lower weight(1.5kg) and they're all smaller then regular laptops(13 inch is the highest).
while the performance is somewhat less then that of a core2 laptop they're more then capable of internet/pictures/email type stuff and the nvidia "ION" based netbooks that are just coming out now can do some more intensive stuff like rendering HD video(they all have HDMI out aswell) and games.
ION based nebooks arent officially released yet (companies are waiting for windows 7 at the end of october), to see the performance you can get from this new chip see this
youtube video.
here are a selection you may want to consider:
asus Eee pc, asus was the first to use the atom processor, this is the most "average" netbook about. you can get it for around £270.
Dell Inspiron Mini, dell have a range of netbooks, theres nothing special about these either, they just look nice. they start from £200. Edit: take this with a pinch of salt tho, i've heard many people bitch about the build quality of dells laptops.
samsung n510, this is the first "ION" out(same one in the video), do some googling and you'll find it. i saw one for £390 somewhere.
HP/compac Mini 311c,this is the other "ION" thats close to release and its availabe from OCUK (preorder), imo its slightly better looking, if its the HP version not the compac, unfortunatly OCUK are stocking the compac version, i think the HP version will be out with the release of windows 7 tho.
heres the link to the product page on OCUK, £315.
Sony VAIO P-series, this one is much more expensive then the previous and has less performance but is retardedly good looking just take a look at
this. its not very practical tho, theres a mini trackball in the middle of the keyboard rather then a touch pad which is anoying, and the screen is obviously smaller. however there are some really nice things about it, you can have the cross media bar interface(PS3 and PSP GUI), they all come with 2 gigs of ram(have more stuff open at once and have vista pre-installed) and they come with solid state drives(tho 60gb isn't much). £700.
