That notebook is actually the Toshiba A33-4M4, Staples made an error, but the price is right - see my thread also in this forum about it - and full specs at www.toshiba.ca
(sometimes Tosh sells it direct with a spare battery and case). I tried it at F Shop and its a really nice machine, very good screen, it was $2200 about 2 months ago. But missing a firewire port IEEE-1394, which may not be a big deal. I think there are very similar Tosh models that have the 1394 and a third USB port, so maybe a new model is coming. I'd also like another USB port, but not a big thing. I downloaded some special music software (it will be my main program) onto the A33 and it ran it fine. I notice F shop no longer carries the A33 so I wonder what is going on, seems to be a blow-out sale.
Check Dell.ca for the deal on 5150 - with SXGA+, a 3.06 CPU, and 80 GB HD it is $1899 - also the battery lasts about 4 hours on this notebook compared to 2 on the Toshiba. The 5150 has been around for about 9 months and is probably being discontinued very soon, that is my guess. Replacement seems to be the 9100 which is a pound heavier and more powerful and about $300 extra. The SXGA+ 9100 is what I'd get. You can get rid of your desktop computer if you have a 9100, A33, or 5150, unless you need a lot of hard drive space for video or something.
I think mechanically the Tosh is a little more solid, and looks better (don't like the Dell gray&blue and too much plastic), also its not as fat as the Dell which weighs 1/2 pound more. The Toshiba may also have better cooling, it did not get very warm when i tried it, it has 2 underside cooling ports and maybe 2 fans and sits a little high for extra ventillation. The Dell 5100 and 5150 are known to accumulate dust in the CPU heatsink after 6 months or so and should be blown out weekly with an air can to prevent overheating problems.

Both are good deals, I can't make up my mind! Also there's the 9100, and Toshiba M35 (not available in Canada).
I'm near Vancouver, where are you?
