no its not.
i do like sony vaios, but try to avoid celeron. for your needs, its probably more than sufficient, but you'd do much better with a centrino.. better battery life, and more powerful.. will last a lot longer than the celeron (technology wise..). if you have $900 to spend, get a nice new laptop thats thin, light, and good on batteries.. don't go the p3 route.
i don't really know of any good places for laptops.. but i'll check newegg...
ok well here are 3 good choices. in terms of weight they're all about the same.. 6.5pounds (a bit heavy...) but they have different advertised battery life.. i'll rank them highest to lowest..
1) ASUS A3Ac w/Combo NoteBook Intel Pentium M 740(1.73GHz) 15.0" XGA 512MB DDR2 533 60GB 4200rpm DVD/CD-RW Combo Intel GMA900 - Retail $939.00
($839.00 after $100.00 Mail-In Rebate)
this notebook has an advertised battery life of 4 hours! not too shabby. (you'll prolly get close to that since you don't do any gaming..) sufficient ram, speed, and HD space for you (HD a bit slow.. but no big deal..). if you like widescreen, you might not like this.
2) well actually there are 3 tied for #2. they're all acer. same battery life. differ a bit in performance and price. these notebooks however only have an advertised battery life of 2 hours! if you're willing to live with that, then they're fine choices as well.

of the three i listed.. probably the first one is best...
