It all comes down on what you need. For me the HP has a card reader too, but not the CF type, (I have a PCMCIA 1GIG mircodrive) so won't be needing it. Tv tuner (who cares?, so you can recored stuff from TV) RAID, (it depends in which your getting 0 or 1 each has its pros and cons, don't need it either, if you need it for space or back up get an extenral drive (just bought an external Maxtor 250Gig 7,200 rpm drive!) Subwoofer & speakers, I mean the HP's have nice speakers, but then again you'll never get desktop quality sound!
Interesting titbit from a site about Raid:
Do you really want RAID enabled?
Probably that answer is no.
First, RAID can only enabled if you purchase 2 hard drives and purchase Windows XP from us. Otherwise, you can set RAID up yourself before you install Windows.
Second, RAID requires hard drives of the same size (if not, then it will ignore the extra size on the larger drive), and the drives should really be the same speed for optimal results.
Third, RAID adds an extra layer of complexity and ties the hard drives to the laptop (data is only readable when drive is connected to the laptop).
RAID 0 (Performance):
Approx. 70% faster than the single drive when reading and about 30% faster when writing.
If one hard drive fails, all data is lost
RAID 1 (Reliability)
If one hard drive fails, no data is lost and no downtime is experienced.
Approximately 30% performance hit when writing to the array. Minimal penalty for reading.
Since the contents of the first drive are stored identically on the second, the size of the array is the same size as a single hard drive
Related to that -- the hard drives will do writes together, making the double the noise.
