My current laptop is getting to the stage where it's fine for using MS Office, iTunes and browsing the web but anything more resource dependent causes it to get sluggish. Now I'm expecting the anti-laptop crew. Please do refrain from rioting but I much prefer them to desktops. Being able to move anywhere and still work is very important for me. I regularly go to a company and need to show them something or when I'm going on the train for a few hours I can get some work in. The budget is around £700 but I don't want a huge lump. Something light and thin is what I'm after. I've done a big search but everything is very similar. I was almost ready to push the button on a MacBook Pro but thought there may be something that I've missed and is better, so that's why I'm checking here. Any suggestions whether they be advising me to get something or to not get something would be great! Cheers.
