You can access your PC/laptop remotely using just about any tablet, not just the iPad as some would have you believe. RDP has been around for a long time and it didn't come from Apple.

Check out Google Docs for making your documents available to you from the device of your choice, not just tablets.

E-reader software (Kindle, Kobo, etc) is available for the device of your choice. However, as haigha pointed out, e-Ink devices are much much nicer to read and use.

Flash is supported on the device of your choice, as long as it's not iPad. Whether this is important to you depends on the web sites you need to access.

I'd also suggest to try to type/edit a meaningful document using a tablet. It may or may not be to your liking. Some tablets accept an external keyboard but as far as I'm concerned, tablet + keyboard = netbook.

You won't be able to fit most tablets in your pocket like your phone. If you'll be carrying a briefcase or backpack anyway then it's not a big deal.

If you are one of the 6 or so people in the world that has a optical molecular tweezer and need to let your 6 year old daughter play with it then the iPad is the only choice at the moment. Otherwise, never mind.
