I would go and look at them in Dixons or PCWorld. The 17" Laptops are pretty big so may be an issue if you want to travel with it regularly.
As regards the upgrade, I personally wouldnt buy a laptop less than 1024 in height but it depends on how and what you use the PC for. If you think about images posted here that are 800 pixels high, with the usual clutter in the standard browser app you will have to scroll to see the full image if your screen is less than 1000 pixels high.
Cheers again Noah ... this will run & run a bit ... went to PCWorld yesterday to compare side by side and again today with Jill (lovely place ... NOT) but she thinks the 15.4" should do nicely and who am I to argue ... except I do rather like the idea of the bigger screen and mobility is second to photobility ... probably ?
Also went back to look at the Sony VGN FE11 s ... at £899.99 can this be beaten ? Such a lovely looking machine too ...
Laptops are a favourite of ebay scammers so I'd make some checks before paying. Look up the address you are given to see who lives there.....get a phone number and speak to the seller.....look to see what they have sold before. 50 feedbacks for 10p items bought and then selling a laptop is not good
A bargain price from Nigeria or Latvia or somesuch might make you think too
I've used ebay a lot but I'd not consider it for a new laptop.
