Miscellaneous laptop discussions : WHICH Vaio P-Series is for me???

WHICH Vaio P-Series is for me???

First, let me say: I come to the cnet forums because the other people HERE are so much more educated than I am in personal electronics. I'm an expert at what I do (landscaping) and bow down to the experts that understand computers. That said, I hope that some kind individual will read this post and help me make the right decision, based on my needs.

I just saw, with LUST in my eyes, the Sony P series of wee computers that are just launched and reviewed by cnet. I want one! But, I don't know which one (there are two models.)http://www.sonystyle.com/webapp/wcs/stores/servlet/CategoryDisplay?catalogId=10551&storeId=10151&langId=-1&categoryId=8198552921644600396&parentCategoryId=16154#

This is what I need: a very small, very portable computer because I travel so much. All I ever do on a computer is answer emails and surf the web. I have two 17" screen laptops that are staying put; they are a bummer to keep lugging around the globe. On those two, I have my Zune music files and my e-Reader book files. And please, I do not want a Blackberry or any phone-type thing that has a 2" screen that I have to suffer reading emails!

Every once in a while I create a Word document and read a pdf file that someone has sent me but that's it.

What I do NOT do: I do not and never will do any of the following: watch Youtube or other silly videos. I will NOT Facebook, Twitter, MySpace, blog or any other waste of my time. I am forced, because of friendship, to follow one person's blog and that is all the indulgence that I will allow. I don't download tv shows or watch movies on my computers, either. Don't burn/rip music or burn photos onto any CD's (that's what my flash drive and back up hard drive are for.)

And before anyone gets snarky and thinks I don't "have a life" because I don't spend it in front of a computer, that's just plain silly! I just believe in actively particating in life, not passively.

So, here's Sony's 2 alternatives to the new P series:

The $900 dollar ones have this: Intel® Processor (1.33GHz)
Genuine Windows Vista® Home Basic

Model Features: 8" display with XBRITE-ECO™ LCD technology, 2GB RAM, 60GB HDD, 1.5 lbs., GPS, integrated mobile broadband, glossy Onyx Black, Bluetooth® technology.

The $1,200 dollar ones have this: Intel® Processor (1.33GHz)
Genuine Windows Vista® Home Premium

Model Features: 8" display with XBRITE-ECO™ LCD technology, 2GB RAM, 64GB SSD, 1.4 lbs., GPS, integrated mobile broadband, glossy Garnet Red, Bluetooth® technology

The only difference that I can see is the Vista one, of Home BASIC with 60GB HDD or Home PREMIUM with 64GB SSD.

Please, what is the difference between BASIC and PREMIUM Vista and what in the world is HDD and SSD??? It's only a $300 difference between the two and I've always been taught tha t"Bigger is better" but I don't know if the more expensive P series will just be a waste for what I want to do with this laptop.

Thanks to anyone who reads and responds to this query.
