Hi, I have a Toshiba Satellite L30-10X which is struggling to keep up. I have a Mobile Broadband dongle on Virgin which I use when on the move or when not in a wifi area. I'm looking for a laptop into which I can insert my Virgin SIM card and forget about it - however when wifi is available I'd prefer the laptop to use wifi rather than use up my allowance. And ideally I'd like it to do the software updates (windows, anti-virus, google calendar synching) only when connected to wifi and a "proper" broadband connection. Some of the software I use really needs a laptop rather than a netbook (MS Publisher; Sibelius). I watch a few movies, but this isn't that important to me. I don't do gaming. I often travel by train and find the 15.4" screen a bit bulky - would prefer 14". Can anyone advise on a suitable machine? And would it make sensible decisions about wifi/wwan usage? Thanks in advance.
