I too will be keeping a laptop, you cannot totally do without them especially if you use other software e.g. AutoRoute, ACSI DVD/Mapping (although you can get an ACSI 'App'), my SatNav updates etc. so need a laptop for this sort of stuff. Where the iPad comes in handy is that it has multiple functions which can save you carrying loads of technology e.g.
As stated above, use it to do your Emails, Skype friends & Family, do your online banking, browse the web and basically most of the usual stuff you would do on your laptop. However, and this is where the portability (size and weight) comes into it's own, read iBooks (even download your Kindle Library if you have one) so now you do not need to carry your Kindle, download your music library from iTunes (I have my whole music collection on my iPad) and so don't have to carry an iPod, takes pictures and videos so don't have to carry a camera (Picture quality is fantastic and you can store up to 5Gb in iCloud for 'Free'. If you need more space you can pay to increase the storage limit).
So, if you already have a laptop that works fine and does everything you need then keep that and invest in an iPad, best of both worlds
