t42: 15' XGA or 14' SXGA+

[msxpip]

Please pardon me if this has been asked before, but I'm in the process of purchasing this unit or looking for alternative suggestions :-

T42 2378FZU -- PM1.7, 512MB, 40 GB, 15" XGA, 1 yr warr.

Any advice ? I'm not sure if this is Flexview (actually I don't even know what flexview is?)

My other option was to get an X40 instead or a T42 with a 14 inch SXGA.

Thanks
