I love my Toshiba laptop. I bought my first one primarily because of its keyboard. The keys felt more like a PC keyboard and were easier to type on than any laptop I've tried before or since. If you do a lot of writing or coding then this is an excellent feature/benefit.
Deminsions and weight are also perfect. It's sleek and weighs just under six pounds. Even if you don't have a case, it's convenient to carry under your arm.
The batteries these models come with now are also great. I can usually get three-and-a-half to four hours out (which makes the screen a little less bright and makes multitasking a little slow--which is no problem when I carry it around to write with). And if I want to listen to music, I've still got a good three hours, give or take fifteen minutes (assuming I use my headphones).
I've got the media center edition, which has Media Player buttons on the side (the buttons are also compatible with Napster, but I haven't gotten them to work with Rhapsody yet). And the screen is just right for a mini movie-screen (proportionally, it's almost the same dimensions as the bigscreen).
I could keep going on about this laptop but I won't. Just know this: it's my favorite computer--fave brand and model--ever. Period.
So buy one already!
