If you really don't want to play games or use higher end video programs you might like the 14" widescreen HP DV1000 series (brand new).
All 3 of the notebooks you mentioned have dedicated video memory which is preferable and I would order 64mb to have the best ability to use the notebook in the future as you can't add video memory later (and 64mb is only 50-75 more than 32mb if offered and you order custom).
Note that the HPZT3000 and Compaq X1000 are the same notebook but have a different appearance. Being in business you might prefer the all black interior (with silver touchpad) of the HPZT3000 but I have the Compaq X1000 -- see X1000forums.com for all the information you need on best ordering specs to get the best value and all the discounts (100 custom mail in rebate through 12/1/04, 3% fatcash portal money back deferred (via Paypal), 6% APP student discount or 12% employer discount if qualified (hpshopping.com).
The Toshiba M35 is a great notebook and I considered an older model when I bought my X1000 --but if you get one get one with the Trubrite LCD and dedicated video memory (not shared).
Toshibas with DVD burners are multiformat. HP was DVD+ only until recently (and many retail models still are) but you can get the multiformat DVD burner at hpshopping if you want it.
Many people are fine with a CD-RW/DVD ROM though at up to $200 less.
Ordering custom you can get 256mb RAM 1 stick and get a PC2700 512mb RAM stick for the 2nd slot under $100 yourself to save money to go to 768mb (on sale at Best buy through Saturday for 79.99 after rebate for Kingston PC2700 512mb Notebook RAM -- I have one in my Compaq X1000).
I would not recommend the Dell 600m as much as the two others as it has some heat issues around the touchpad area (try out one at a kiosk for yourself at a mall --the Stoneridge Mall in Pleasanton, CA at I580@I680 has one. Cnet had this model rated lower (under 8.0)
The Toshiba M35 also has some heat issues (they have raised feet in the back for more airflow) and you can feel a bit of heat around the touchpad also (at least on the older models --try a current one in a retail store).
The HPZT3000/Compaq X1000 has a great keyboard (not up to IBM but still very good) and its only real drawback is only the ATI 9200 video card with up to 64mb dedicated RAM but you won't need more than that for your use (and the Toshiba tops out at 64mb dedicated video also).
Get a 5400rpm hard drive custom for up to 50% better seek time (and faster operating system boot times) for only $250$50 over a standard 4200rpm hard drive at the same capacity (HPshoppping has both in 60gb and I think some offer 80gb in both speeds).
Keep in mind the Dell 600M has a amaller LCD (14" square?) so it is lighter (5.5 pounds or less) while the Toshiba M35 and HPZT3000/Compaq X1000 have the 15.4" widescreen (great for DVD's, more Excel spreadsheet columns) at 6.2 and 6.5 pounds each.
Note also that HP has the Briteview LCD option in XGA resolution available for nearly all its notebooks at hpshopping.com (or Compaq -- same website) which is equivalent to Toshiba Trubrite. Or, you can go up to SXGA or UXGA resolution (but not Briteview). Some retail models have Briteview but others do not.
If using the notebook at a business with outside light behind you or harsh flourescent lights overhead you might NOT want the Briteview/Trubrite but otherwise for home use or consumer use you would want the extra clarity and contrast this LCD coating offers.
Hi.. need help to make a decision on which these three laptop will be the right choice.
1. Toshiba M35x-S349
2. Compaq x1000
3. Dell Insipron 600M
For the price, Dell is the lowest. But on the specs, they are very similar, probably a little different here and there or i might be wrong. Any comment? anyone owns any of them? how's the performance and reliability?
My profession is in accounting field. Not using it for gaming.
Thanks !
