Pros and Cons of a desktop processor on a laptop
Mobile P4 processor or a "normal" P4 processor?

I plan to purchase Toshiba Satellite within the next few days. One particular model is powered by Mobile Intel Pentium 4 running at 1.8 GHz while another is powered by Intel Pentium 4 running at 2.4 GHz. Note that the latter is a desktop processor tonked into the laptop.

Battery time is not an issue because it will plugged into the power socket 90 percent of the time. Both the laptops have identical features - fitted with GeForce 4 graphics cards :)

My dealer is seriously discouraging me from buying a laptop with the desktop processor (2.4 GHz). He reckons that the processor will overheat and cause freezes/crash etc.

Is there any truth in what the dealer is saying? Should I go for the mobile P4 processor running at lower GHz, as recommended by the dealer? Both the laptops have similar pricing.

I would definitely go with the mobile processor. A partner of mine has one of the first 16inch Sony Vaio's. They were originally released with the desktop processor.

Last Xmas, I bought the new version of the same computer. Mine has the mobile processor. It's like night and day. Not only is the desktop version more problematic, the bottom of the laptop gets so hot, you can't really work with it in your lap.

My Toshiba is too heavy to keep it on my lap anyway (3.8 kgs) - so I will probably be using it on a table or the bed.

I just don't like the idea of losing out on 600 MHz of processing power.. I would love to hear anybody who has had good experiences with a desktop processor on a laptop.

One more question -

Is the performance of a mobile P4 processor equal to a desktop P4 processor running at the same clock speed?

I'm sitting here with the toshiba on my lap now. I have not had any problems with the 2.4 desktop processor.

Somehow it is actually not as hot as my old toshiba, which used to feel like it would burn my lap. I've been sitting here for about an hour and it's only a little warm...so little I don't notice it at all. I would think it would get hot, but it doesn't. They might not all be this way, but mine is. I should say the the room I'm in is generally cool, so if your room is warm it might be a little worse.

Even the fan, which some have complained is loud, doesn't bother me. It is a little loud when it comes on, but the sound is more bearable than my old toshiba.

The screen size and power is just awesome. I can safely say I will never own another desktop after this.

The only negative I can see is the weight. I don't really take it out of the house, so it doesn't bother me, but I wouldn't want to do any real traveling with this thing...10lbs gets heavy fast.

10 lbs? Isn't that equal to 5 kilograms? Boy - you sure need a crane to lift that piece. What is the model number? I am looking at 2410 series for the mobile processor and 2430 series for the desktop processor.

I have read some good user reviews of Toshiba laptops at CNET.

The Toshiba laptops I have seen have a good set of speakers (especially Harman Kardon speakers on 2430 series). Other brand speakers sound like tin cans. So Toshiba it will be - I am not sure about the model.

Toshiba Satellite 1955-S803. I just checked and the processor is actually 2.5, not 2.4 as I said earlier.

This is my second toshiba, and they seem really good to me. The last one my wife dropped on the pavement. It hit hard and the dvd player tray was ripped right out of it. I picked it up and literally crammed the tray back in.

It would never stay shut, but it worked fine so I brought out the trusty Duct Tape and it's been working fine for over 2 years. I just replace the tape when I load some new software :)

I have a 10 pound Dell. I will get a lighter model IBM next time. 10 pounds is just too much for something you have to tote around. It may not seem like it, but there is a huge difference in a laptop between 5 and 10 pounds.

If you aren't going to tote it, then why get a laptop at all. Get a desktop machine.

With a desktop...

- I can't work from the couch
- I can't use it at the pool
- I can't sit on the deck
- I can't move to the kitchen and chat while dinners being cooked
- I can't bring it to work every now and then

I'd say if you can afford a laptop with a big screen and plenty of power, why would ever want to be tied to the desk?

Ever since my first laptop I've used it for 100% of my work. 90% of which I do on the couch in front of the tube with a beer in hand.

Depending on your needs you may require a desktop, but I can tell you for sure that I will never buy one again.

"I just don't like the idea of losing out on 600 MHz of processing power.. "

You are incorrect in this statement. You cannot compare a mobile processor laptop to a desktop processor laptop. There is not a 600 MHz difference. In fact, the mobile processor might even be faster depending on the applications you are running.

If you are multitasking, the mobile processor will handle things better. The desktop processor does not handle major multitasks simultaneously well. When running major, multiple applications, the desktop processor will generate heat (because its processing a lot of data). To compensate and reduce this heat buildup, the desktop processor actually slows down. So, your 2.5 gig processor is now sub 2.0 processing because of the heat buildup.

I'm sure if you were to reasearch desktop vs. mobile laptops on the internet, you will find some benchmarks and performance evaluations.

Purchased Toshiba with MOBILE P4 1.8 GHz. Why take a risk with such a large investment?

So far, so good. Quite happy with its performance (GTA3 runs great!)

I use a "weirdo" generic brand of laptop called a Desknote. It uses regular CPU and memory... It's got extra ventilation and does not include a battery. It's a notebook-shaped desktop PC. It runs hot but I've had no problems with it. Had it for a year. It's a "geek machine."

Battery life has no meaning to me. Even 2 hours is not long enough. I'm either plugged in or not using a computer.
