Personally, I like something a bit bigger than a pad. I have a Sony Vaio laptop that I take with me everywhere. It plays my music, I watch DVDs on it, surf the net, type a ms entry and store it on a CD if I don't want to keep it just on the hard drive (or don't want to over-burden hard-drive memory). The battery pack, fully charged, gives me about two hours of stored power w/o need to plug it in anywhere. If an outlet is available, I generally do plug it in, however, just to keep the battery charged. Right now I'm having a McCafe at the local McDonald's in my neighborhood which offers free WiFi from ATT. You see me on the street, there's usually a canvas computer shoulder-bag I'm carrying.
Like I say, this is just a personal prference. Working on this lap-top feels pretty much just like working on a desk-top model. But, again, I'm no mayven
on the subject.
