If you need a little extra computing power this tax season, Dell is currently offering free upgrades to big 19-inch screens and extra memory with its XPS series packages. In particular, we like the spunky little XPS 200, which Dell says is 79 percent smaller than its big brother, the XPS 600. The slimmer case means this model can be used in kitchen areas and other public spaces without looking like a hulking gray elephant. On the performance side, its optional dual core processor and all that memory means it can crunch your numbers and juggle, say, music or video, with aplomb. It starts at $999. Pray for an IRS refund.
