Beyond that, it's definately big enough to no longer be the "oh it's so small it's so cute" but I think the screen real estate is going to be worth it.
A new computer has never been a happy thing for me. There is always been one problem or another. My machine that had a hard drive randomizer and would only run X with the turbo button off. My laptop that came with a bad floppy drive. The computer that went through 3 disk drives, 2 net cards and 2 power supplies, complete with impresive puffs of light and smoke. The laptop that would only work if you knew where to squeeze it right. My last viao, which had a pcmcia CDrom and no floppy, which made installation of linux fun. And now this one.
Here's hoping it's just the media (which plays nice with dell CDRW)
