Here is direct Torrent and download links for Ubuntu 11.04, have fun 🙂 I have provided both Torrent links (which I prefer) and directly downloads:

Note: With this release, the Desktop and Netbook releases are merges with a single Unity interface, hence there is no sepearate Netbook edition. If you want to Install Ubuntu on a Netbook, download the Ubuntu Desktop Edition. If you have any of the older Netbooks, pick the 32-bit version. Download the 64-Bit version only if you have a newer processer like the AMD fusion which support 64-Bit.
